To our shareholders,

Throughout our 145-year history, we have helped our 
clients grapple with complex challenges. 2015 was 
a case in point. Financial markets tumbled, foreign 
exchange rates fluctuated dramatically and geopolitical 
turmoil swept through continents. These volatile 
and uncertain conditions contributed to a dynamic 
environment full of threats and opportunities for our 
clients. Our areas of strength — risk, strategy and 
people — have never been more relevant or important. 

145-year

HISTORY OF  
LEADERSHIP AND  
INNOVATION

Clients sought our deep expertise, our understanding of their businesses, our 

creativity and our unwavering commitment to client service. 

Our company has considerable advantages that enable us to grow in varied 

market conditions. Most importantly, we have great people. We are, after all, a 

professional services firm. The intellectual capacity and creativity of our colleagues 

is our product. As I visit our offices around the world, I am always impressed by the 

intelligence, ingenuity and dedication of our colleagues and our leaders. 

We make a positive impact on the businesses, people and societies we serve by 

providing guidance and support during critical moments... that is a powerful 

purpose that unites us all. Our 60,000 colleagues — actuaries, brokers, consultants,  

subject-matter experts and other professionals — advise clients on many of the 

most complex issues of our time: responding to natural catastrophes, providing  

for retirement security, attracting and retaining the best people and enhancing 

cyber resilience — to name a few. 

We manage our company with three specific constituencies in mind: our clients, our 

colleagues and our shareholders. We have sought to strike the appropriate balance 

between rigorous execution in the short term and strategic investment for the long 

term. These twin objectives are reflected in our return of a record amount of capital to 

shareholders in 2015 coupled with our substantial investments to grow our business.

Though we live in challenging times, I am confident that our inherent strengths — 

extraordinary people, a cohesive culture and a restless commitment to finding a 

better way — will fuel our firm’s long-term growth.

6 years

OF CONSECUTIVE  
OPERATING MARGIN 
GROWTH IN BOTH 
SEGMENTS

ANOTHER YEAR OF STRONG FINANCIAL PERFORMANCE

Building on six consecutive years of strong performance, Marsh & McLennan 

delivered another year of robust financial results in 2015. 

We generated 4% underlying revenue growth with healthy increases at all four 

operating companies. In each of the last six years, we have grown consolidated 

underlying revenue in the 3% to 5% range. Acquisitions have added an additional 

two percentage points on average over that same time period. 

Adjusted operating income1 rose 5% to $2.5 billion. We continued our track  
record of operational excellence by increasing adjusted operating margins.  

In 2015, our consolidated margin accelerated 100 basis points, to 19.1%,  

our highest level in more than a decade. 

“We are a brains business. We manufacture 
ideas and solutions. We collaborate to 
create a value proposition greater than the 
sum of its individual parts.”

Our earnings per share increased 12%, and adjusted  

EPS grew 8% to a record $3.05. We achieved  

these results despite $0.18 of negative impact  

from the effects of foreign exchange. On a constant 

currency basis, our adjusted EPS growth was an 

impressive 14.5%. Since 2009, our adjusted EPS  

has grown at a CAGR of 13.5%, in line with the  

13% long-term target we established in 2010. We  

delivered this outstanding record of performance  

while overcoming approximately $200 million 

of foreign exchange headwinds during this six-year period, representing  

a yearly average of $.04 per share.

Risk and Insurance Services revenue of $6.9 billion reflected an increase of 3% on 

an underlying basis. Adjusted operating income rose 3% to $1.6 billion, with the 

adjusted margin expanding 90 basis points to 23.3%, the highest in more than a 

decade. Adjusted operating margins in RIS have improved every year since 2007.

Marsh’s underlying revenue growth of 3% reflected increases across all major 

geographies. This was Marsh’s fifth straight year of underlying revenue growth  

of at least 3%.

Guy Carpenter’s underlying revenue growth of 2% was a solid result given the 

dynamics in the reinsurance industry.

in this letter, please refer to the Company’s Form 8-K, dated February 4, 2016, available on the Company’s 
website at mmc.com.

Consulting produced revenue of $6.1 billion, an increase of 5% on an underlying 

basis. Adjusted operating income rose 4%, exceeding $1 billion for the first time 

in our history. Consulting’s track record of higher adjusted operating margins 

continued in 2015, expanding 80 basis points to 17.3%. Since 2010, the adjusted 

margin has improved by 600 basis points. 

Mercer’s underlying revenue growth of 4% was strong and marked the fifth 

consecutive year of growth of 3% or higher. 

Oliver Wyman’s underlying revenue growth of 7% in 2015 came on top of 2014’s 
outstanding growth of 15%.

“Since 2009, our adjusted EPS has grown  
at a CAGR of 13.5%, consistent with our  
long-term target set at Investor Day in 2010  
and reaffirmed in March 2014.”

OUR COMMITMENTS TO SHAREHOLDERS 

In 2015, we returned a record level of cash — over $2 billion — to our shareholders. 

At our Investor Day in March 2014, we made three commitments to shareholders: 

1)  Grow adjusted EPS at a long-term CAGR of 13%; 

2)  Increase our dividend per share by double-digits every year; and 

3)  Reduce our share count every year.

We continue to deliver on these commitments. Since 2009, our adjusted EPS has 
grown at a CAGR of 13.5%, consistent with our long-term target set at Investor Day  

in 2010 and reaffirmed in March 2014. In 2015, we increased our annual dividend  

by 11.3%, exceeding even the 10.4% increase in 2014. And our share count declined 

for the second straight year. 

Bottom line, Marsh & McLennan delivered another strong year of financial 

performance in 2015.

OUR VIEW OF THE MARKETS 

I am proud to have spent the past 30 years working in the insurance industry, both as 

a broker and as an underwriter. In my view, the insurance industry plays a crucial role 

in spurring economic growth, the taking of risk and promoting innovation. On the 

upside, insurance enables commerce to thrive. Satellites are launched. Skyscrapers 

are built. Medicines are invented. On the downside, insurance is a vital buffer 

enabling lives and livelihoods to be rebuilt following loss.

Like the broader market, these are dynamic times in the insurance industry. 

Insurance companies are dealing with significant structural change. We have seen  

large-scale M&A, senior management changes, a reduction in the underwriting 

appetite at several companies, an infusion of alternative capital and a willingness at 

some firms to reconsider reinsurance as a way to reduce volatility.

Intense competition and excess capacity coupled with challenging returns have 

led to orderly pricing declines. This trend has played out for several years and is 

fundamentally good for our clients. As insurance markets evolve and consolidate, we 
believe that the advice of a broker will be all the more important to clients trying to 

make sense of industry change. Advisors with the deepest experience and broadest 

capabilities stand to benefit from a flight to quality as clients seek trusted advisors 

with the right skills to help them navigate through the uncertainty.

Dynamic change also creates exciting opportunities for our consulting businesses. 

The ongoing development of economies around the world and the impact of key 

socioeconomic trends should accelerate the need for our advice and solutions. 

In mature markets with aging workforces, both companies and individuals wrestle 

with uncertainty as increasing amounts of responsibility shift to individuals for their 

retirement, health and investment decisions. Mercer is well-positioned to assist 

people, companies and governments in developing innovative solutions to adapt to 

the change wrought by powerful demographic and economic trends. 

Global volatility provides significant opportunity for Oliver Wyman, a leading 

provider of strategic advice and solutions to the C-suite. With deep industry 

expertise, Oliver Wyman has demonstrated its ability to help clients navigate the 

changing strategic and regulatory environment in sectors as diverse as financial 

services, healthcare, aviation and energy. 

We remain optimistic about our ability to help clients face the significant  

challenges of our time. 

OUR LONG-TERM GROWTH PHILOSOPHY

Our goal is to become one of the very best companies — not simply in our industry 

segments — but in the world. To get there, we must demonstrate our ability to 

generate sustained growth in revenues and profit, drive innovation and make  
Marsh & McLennan a great place to work.

Each of our operating companies is a global leader, helping clients address the 

issues of the day. By enabling our clients to succeed, we expect to produce strong 

$2 billion

AND SHARE REPURCHASE

growth in our revenues, earnings and cash flows over the long term. We also expect 

to deliver, over time, significantly higher earnings growth than the S&P 500, with 

lower capital requirements and reduced risk. 

Our revenue growth is driven by the investments we make. We have invested 

organically and through acquisition to enter new segments, broaden our 

geographic footprint and deepen our capabilities. 

Since 2009, we have invested nearly $7 billion for growth and efficiency.  

This includes:

•  115 acquisitions and investments totaling approximately $4.6 billion; and  

•  Capital investments of $2.2 billion.

“Our goal is to become one of the very best companies —  
not simply in our industry segments — but in the world. 
To get there, we must demonstrate our ability to generate 
sustained growth in revenues and profit, drive innovation 
and make Marsh & McLennan a great place to work.” 

In 2015, we completed more acquisitions than in any year in our history. A good 

example of our acquisition-led growth strategy is the build-out of Marsh & McLennan 

Agency (MMA). Since 2009, MMA has closed 51 transactions and invested over 

$2 billion. In 2015, MMA acquired six agencies across the United States, including 

the highly regarded MHBT in Texas. MMA now has a business approaching 

$1 billion of annualized revenue, which represents a top-10 independent agency 

in its own right. We believe we can replicate this success in overseas markets, 

including the United Kingdom. To strengthen our platform in the UK, we acquired 

the publicly-traded Jelf Group, a leading UK retail broker, in 2015. 

On the organic investment front, the build-out of our Mercer Marketplace 

Healthcare exchange (MMx) is another developing success story. MMx provides 

access for approximately 1.5 million lives and helps our clients control costs while 

offering their employees choice, flexibility and an engaging user experience. 

These are just three of many examples of how we are constantly looking forward 

and investing to position ourselves for sustainable, long-term growth while also 

producing strong annual performance.

7

The diversity of our geographic footprint is a particular strength of our company 

and an important driver of our long-term growth. 

Marsh & McLennan is well-established in most large diversified economies that are 

particularly important to our long-term success. Moreover, our vast global network  

positions us well in virtually all emerging markets and growth economies. While 

volatile in 2015, these markets remain a long-term driver of growth because of the 

under-penetration of insurance and consulting services. 

An important part of our strategy is to preserve flexibility and maintain balance.  
We are managing the business to consistently deliver excellent results while 

continuing to invest for the long term. In this uncertain global environment, we 

have preserved the capacity to invest opportunistically during periods of stress. 

This is the principal reason we have maintained financial leverage at lower levels 

than our peers and the overall market. 

“Each of our operating companies is a  
global leader, helping clients address  
the issues of the day.” 

Lastly, we want to be relentless in our execution. Rigorous execution is every bit as 

important as strategic vision. We are perpetually dissatisfied with the status quo: 

We never stop searching for a better solution, whether it is a new insurance product 

to address an emerging risk, a more streamlined digital solution to optimize 

healthcare choices or a more refined set of analytics to deliver insights to clients. 

We have a mantra at the company that there is always a smarter way. Every day, 
every week, every month, we need to find it.

Our dual focus on short-term execution and long-term investment should increase 

the distance between us and our competitive set. 

OUR COMMITMENT TO INNOVATION

We have a storied history of innovation. In the early 20th century, our founder, Henry 

Marsh, revolutionized the insurance industry by creating the concept of an insurance 

broker who acted on behalf of the client rather than the insurer. In the 1920s, Guy 
Carpenter (yes, there was a man named Guy Carpenter) introduced the novel idea 

of insurance for insurers — or reinsurance. After World War II, William M. Mercer 

invented the notion of a defined benefit plan. In the 1980s, Alex Oliver and Bill Wyman 

created the idea of a management consulting firm built on industry verticals. 

8

Thanks to the pioneering spirit of our colleagues, Marsh & McLennan has been 

at the forefront of innovation for over a century. The next frontier will almost 

certainly revolve around technological innovation. Marsh and Guy Carpenter have 

made substantial investments in technology platforms to benefit their clients. For 

example, Marsh acquired Dovetail, a technology provider with an advanced cloud-

based platform that enables agents to trade with multiple insurers and bind policies 

in real time. Guy Carpenter recently launched GC ReBid, a proprietary real-time, 

online reinsurance auction platform where markets can openly bid for participation 

on reinsurance placements. 

Similarly, Mercer has launched an array of digital and mobile solutions that include: 

Mercer Match, a mobile application that utilizes gamification and neuroscience 

to match individuals with job opportunities; Mercer Harmonise, a UK mobile 

application that enables individuals to track critical information about their wealth 

and health in a single place; and Mercer Pension Risk Exchange, an online platform 

that allows pension plan sponsors to monitor buy-out capacity and execute 

transactions swiftly. In a similar vein, Oliver Wyman has launched “OW Labs,”  

which applies advanced algorithms to large data sets to deliver insights to clients 

through customized dashboard applications. 

OUR CULTURE

The diversity of our people contributes to our success and the richness of our lives. 

After all, we are a brains business. We manufacture ideas and solutions. We harness 

our collective intelligence, collaborating across teams, business units and global 

offices to create a value proposition greater than the sum of its individual parts. 

Our colleagues choose to give us their time, their commitment and their careers. 
We understand the importance of creating an environment where we look at issues 

from multiple perspectives and where our people feel comfortable expressing 

themselves and sharing their ideas. 

As I travel around the world, I meet with our colleagues in town hall discussions. 

I urge them to live fully, reminding them that, at Marsh & McLennan, our people 

come first. Their family lives are essential, and their personal growth is as important 

as their professional development. We want Marsh & McLennan to be a vibrant 

place to work; our commitment to working side by side in a respectful, professional 

environment is an important value of our firm.

 LOOKING FORWARD 

I am privileged to serve as the CEO of this great company. I feel fortunate to lead an 

accomplished executive team that is diverse in thought and cohesive in action. It is a 

team that keeps its promises. And it is a team that has delivered year after year.

I am also fortunate to work with a talented and engaged Board of Directors. Under  

Lord Ian Lang’s leadership as Chairman, the Board has struck an excellent balance 

between challenge and support. The Board has been actively involved in the 

development of management’s long-term strategic plans. As part of our efforts 

to expand our global operations, we were particularly pleased to add Maria Silvia 

Bastos Marques, one of Brazil’s leading executives, to our Board in March of 2015. 

Having reached our mandatory retirement age, Ian Lang will step down as  

Chairman at our upcoming annual meeting in May. Ian has brought a global 

perspective, a keen intellect and a politician’s wit to our deliberations. Ian has also 

sought to make the Board accessible to our colleagues by participating in numerous 

town halls in Bermuda, London, New York, Paris, San Francisco and Shanghai. On 

behalf of our entire organization, I want to express our profound gratitude to this 

elegant man for his almost two decades of service to this company, including five 

years as Chairman of the Board. 

Edward Hanway, a member of our Board since 2010, will become Chairman  

this May. Before joining our Board, Ed enjoyed a remarkable tenure as the CEO  

of Cigna Corporation for nearly a decade. I look forward to Ed’s leadership of  

our Board for years to come. 

In closing, I want to thank our 60,000 colleagues whose professionalism and  

hard work are at the heart of this enterprise, our clients who put their trust in  

us and our investors. I try to manage our business with a keen awareness that  

I have been trusted by the owners of our company to look after their investment  

and make it grow. We are always in the market for investors who support our 

balanced approach of delivering strong financial performance today and  

investing for the future. 

Today, we are stronger strategically, operationally and financially than  

at any time in the last decade. I am optimistic about the future of  

Marsh & McLennan. The best is yet to come.

Acting as a broker or intermediary on all classes of reinsurance, Guy Carpenter places two main types of

agriculture; alternative risk transfer (such as group-based captives and insurance pools); aviation &

reserve risk, capital adequacy and return on capital.

Compensation for Services in Risk and Insurance Services

Marsh and Guy Carpenter are compensated for brokerage and consulting services through commissions 
and fees. Commission rates and fees vary in amount and can depend upon a number of factors, including 
the type of insurance or reinsurance coverage provided, the particular insurer or reinsurer selected, the 
capacity in which the broker acts and negotiations with clients. In addition to compensation from its 

4

clients, Marsh also receives compensation from insurance companies. This compensation includes, 
among other things, payments for consulting and analytics services provided to insurers; fees for 
administrative and other services provided to or on behalf of insurers (including services relating to the 
administration and management of quota shares, panels and other facilities in which insurers participate); 
and contingent commissions, which are paid by insurers based on the attainment of specified goals 
relating to Marsh's placements, particularly at Marsh & McLennan Agency and in parts of Marsh's 
international operations. 

Marsh and Guy Carpenter receive interest income on certain funds (such as premiums and claims 
proceeds) held in a fiduciary capacity for others. For a more detailed discussion of revenue sources and 
factors affecting revenue in our Risk and Insurance Services segment, see Part II, Item 7 ("Management's

under administration or management. For a majority of the Mercer-managed investment funds, revenue 
received from Mercer's investment management clients as sub-advisor fees is reported in accordance 
with U.S. GAAP, on a gross basis rather than a net basis. For a more detailed discussion of revenue 
sources and factors affecting revenue in the Consulting segment, see Part II, Item 7 ("Management's 
Discussion and Analysis of Financial Condition and Results of Operations") of this report.

REGULATION

The Company's activities are subject to licensing requirements and extensive regulation under U.S. 
federal and state laws, as well as laws of other countries in which the Company's subsidiaries operate. 

7

See Part I, Item 1A ("Risk Factors") below for a discussion of how actions by regulatory authorities or 
changes in legislation and regulation in the jurisdictions in which we operate may have an adverse effect 
on our businesses.

Risk and Insurance Services.  While laws and regulations vary from location to location, every state of 
the United States and most foreign jurisdictions require insurance market intermediaries and related 
service providers (such as insurance brokers, agents and consultants, reinsurance brokers and managing 
general agents) to hold an individual or company license from a government agency or self-regulatory 
organization. Some jurisdictions issue licenses only to individual residents or locally-owned business 
entities; in those instances, if the Company has no licensed subsidiary, it may maintain arrangements with 
residents or business entities licensed to act in such jurisdiction. Such arrangements are subject to an 
internal review and approval process. Licensing of reinsurance intermediaries is generally less rigorous 
compared to that of insurance brokers, and most jurisdictions require only corporate reinsurance 
intermediary licenses.

The Insurance Mediation Directive was adopted by the United Kingdom and 26 other European Union 
Member States in 2005. Its implementation gave powers to the Financial Services Authority ("FSA"), the 
United Kingdom regulator at the time, to expand their responsibilities in line with the Financial Services 
and Markets Act, the result of which was the regulation of insurance and reinsurance intermediaries. The 
enhanced regulatory regime effected a licensing system based on an assessment of factors which 
included professional competence, financial capacity and the requirement to hold professional indemnity 
insurance. In April 2013, the FSA was superseded by the Financial Conduct Authority ("FCA"). In April 
2014, the FCA’s responsibilities were expanded further to include the regulation of credit activities for 
consumers. This included the broking of premium finance to consumers who wished to spread the cost of 
their insurance. In April 2015, the FCA obtained their concurrent competition powers enabling them to 
enforce the prohibitions on anti-competitive behavior in relation to financial services.

Insurance authorities in the United States and certain other jurisdictions in which the Company's 
subsidiaries do business, including the FCA in the United Kingdom, also have enacted laws and 
regulations governing the investment of funds, such as premiums and claims proceeds, held in a fiduciary 
capacity for others. These laws and regulations typically provide for segregation of these fiduciary funds 
and limit the types of investments that may be made with them, and generally apply to both the insurance 
and reinsurance business. The FCA is currently reviewing its rules drafted to protect client assets and 
client money. If deemed appropriate, the FCA will implement changes intended to provide enhanced 
protection to client funds. 

Certain of the Company's Risk and Insurance Services activities are governed by other regulatory bodies, 
such as investment, securities and futures licensing authorities. In the United States, Marsh and Guy 
Carpenter use the services of MMC Securities LLC (formerly MMC Securities Corp.), a broker-dealer, 
investment adviser and introducing broker. MMC Securities LLC is registered in the United States with the 
SEC and is a member of the Financial Industry Regulatory Authority ("FINRA"), the National Futures 
Association and the Securities Investor Protection Corporation ("SIPC"), primarily in connection with 
capital markets and other investment banking-related services relating to insurance-linked and alternative 
risk financing transactions. Also in the United States, Marsh uses the services of MMA Securities LLC 
(formerly NIA Securities, LLC), a U.S. registered broker-dealer and member of FINRA, SIPC and the 
Municipal Securities Rulemaking Board. In the United Kingdom, Marsh and Guy Carpenter use the 
expertise of MMC Securities (Europe) Limited, which is authorized and regulated by the FCA to provide 
advice on securities and investments, including mergers & acquisitions in the European Union. MMC 
Securities LLC, MMC Securities (Europe) Limited, MMA Securities LLC and Marsh Investment Services 
Limited are indirect, wholly-owned subsidiaries of Marsh & McLennan Companies, Inc.

Consulting.  Certain of Mercer's retirement-related consulting and investment services are subject to 
pension law and financial regulation in many countries. In addition, the trustee services, investment 
services (including advice to persons, institutions and other entities on the investment of pension assets 
and assumption of discretionary investment management responsibilities) and retirement and employee 
benefit program administrative services provided by Mercer and its subsidiaries and affiliates are also 
subject to investment and securities regulations in various jurisdictions, including regulations imposed or 
enforced by the SEC and the Department of Labor in the United States, the FCA in the United Kingdom, 

8

the Central Bank of Ireland and the Australian Prudential Regulation Authority and the Australian 
Securities and Investments Commission. In the United States, Mercer provides investment services 
through Mercer Investment Management, Inc. and Mercer Investment Consulting LLC, each an SEC-
registered investment adviser. Mercer Trust Company, a New Hampshire chartered trust bank, provides 
services for Mercer’s benefits administration and investment management business in the United States. 
The benefits insurance consulting and brokerage services provided by Mercer and its subsidiaries and 
affiliates are subject to the same licensing requirements and regulatory oversight as the insurance market 
intermediaries described above regarding our Risk and Insurance Services businesses. Mercer uses the 
services of MMC Securities LLC in connection with the provision of certain retirement and employee 
benefit services. Oliver Wyman Group uses the services of MMC Securities LLC in the United States and 
MMC Securities (Europe) Limited in the European Union, primarily in connection with corporate finance 
advisory services.

FATCA.  Regulations promulgated by the U.S. Treasury Department pursuant to the Foreign Account Tax 
Compliance Act and related legislation (FATCA) require the Company to take various measures relating to 
non-U.S. funds, transactions and accounts. The regulations impose on Mercer certain client financial 
account tracking and disclosure obligations with respect to non-U.S. financial institution and insurance 
clients, and require Marsh and Guy Carpenter (and Mercer, in limited circumstances) to collect, validate 
and maintain certain documentation from each foreign insurance entity that insures a risk that is subject 
to the regulations. The Company has adopted processes to substantially address FATCA’s 
requirements. Barring U.S. Treasury action to scale back FATCA in 2016, FATCA’s application is due to 
expand as of January 1, 2017 to regulate a broader set of insurance and reinsurance placements, known 
as "foreign-to-foreign" transactions. Though this expansion of FATCA’s reach may be delayed or 
permanently suspended, the Company has begun to undertake measures to also achieve timely 
compliance with FATCA’s foreign-to-foreign requirements.

COMPETITIVE CONDITIONS

The Company faces strong competition in all of its businesses from providers of similar products and 
services, including competition with regard to identifying and pursuing acquisition candidates. The 
Company also encounters strong competition throughout its businesses from both public corporations 
and private firms in attracting and retaining qualified employees. In addition to the discussion below, see 
"Risks Relating to the Company Generally-Competitive Risks," in Part I, Item 1A of this report.

Risk and Insurance Services.  The Company's combined insurance and reinsurance services 
businesses are global in scope. The principal bases upon which our insurance and reinsurance 
businesses compete include the complexity, range, quality and cost of the services and products offered 
to clients. The Company encounters strong competition from other insurance and reinsurance brokerage 
firms that operate on a nationwide or worldwide basis, from a large number of regional and local firms in 
the United States, the European Union and elsewhere, from insurance and reinsurance companies that 
market, distribute and service their insurance and reinsurance products without the assistance of brokers 
or agents and from other businesses, including commercial and investment banks, accounting firms,  
consultants and web search engines, that provide risk-related services and products or alternatives to 
traditional brokerage services. 

Certain insureds and groups of insureds have established programs of self insurance (including captive 
insurance companies) as a supplement or alternative to third-party insurance, thereby reducing in some 
cases their need for insurance placements. Certain insureds also obtain coverage directly from insurance 
providers. There are also many other providers of managing general agency, affinity programs and private 
client services, including specialized firms, insurance companies and other institutions.

Consulting.  The Company's consulting and HR outsourcing businesses face strong competition from 
other privately and publicly held worldwide and national companies, as well as regional and local firms. 
These businesses compete generally on the basis of the range, quality and cost of the services and 
products provided to clients. Competitors include independent consulting and outsourcing firms, as well 
as consulting and outsourcing operations affiliated with accounting, information systems, technology and 
financial services firms.

9

Mercer's investments business faces competition from many sources, including investment consulting 
firms (many of which offer delegated services) and other financial institutions. In some cases, clients have 
the option of handling the services provided by Mercer and Oliver Wyman Group internally, without 
assistance from outside advisors.

Segmentation of Activity by Type of Service and Geographic Area of Operation.

Financial information relating to the types of services provided by the Company and the geographic areas 
of its operations is incorporated herein by reference to Note 16 to the consolidated financial statements 
included under Part II, Item 8 of this report.

Item 1A.      Risk Factors 

You should consider the risks described below in conjunction with the other information presented in this 
report. These risks have the potential to materially adversely affect the Company's business, results of 
operations or financial condition.

RISKS RELATING TO THE COMPANY GENERALLY

Legal and Regulatory Issues

We are subject to significant uninsured exposures arising from errors and omissions, breach of 
fiduciary duty and similar claims.

Our operating companies provide numerous professional services, including the placement of insurance 
and the provision of consulting, investment advisory, actuarial and other services, to clients around the 
world. As a result of these activities, the Company and its subsidiaries are subject to a significant number 
of errors and omissions, breach of fiduciary duty and similar claims, which we refer to collectively as 
"E&O claims." In our Risk and Insurance Services segment, such claims include allegations of damages 
arising from our failure to adequately place coverage or notify insurers of potential claims on behalf of 
clients. In our Consulting segment, such claims include allegations of damages arising from the provision 
of consulting, investments, actuarial, pension administration and other services. These services frequently 
involve complex calculations and other analysis, including (i) assumptions and estimates concerning 
contingent future events, (ii) drafting and interpretation of complex documentation governing pension 
plans, (iii) calculating benefits within complex pension structures and (iv) the provision of investment 
advice, including regarding asset allocation and investment strategy, and management of client assets, 
including the selection of investment managers. Given the long-tail nature of many of these types of 
claims, these matters often relate to services provided by the Company dating back many years. Such 
claims may subject us to significant liability for monetary damages, including punitive and treble 
damages, negative publicity and reputational harm and may divert personnel and management 
resources. We may be unable to effectively limit our potential liability in certain jurisdictions or in 
connection with certain types of claims, particularly including those concerning claims of a breach of 
fiduciary duty.

In establishing liabilities for E&O claims in accordance with FASB ASC Subtopic No. 450-20 
(Contingencies - Loss Contingencies), the Company uses case level reviews by inside and outside 
counsel, an internal actuarial analysis and other analysis to estimate potential losses. A liability is 
established when a loss is both probable and reasonably estimable. The liability is reviewed quarterly and 
adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than 
for legal fees to defend the claim, because we are unable, at the present time, to make a determination 
that a loss is both probable and reasonably estimable. Nevertheless, given the challenges inherent in 
establishing liabilities in accordance with FASB ASC Subtopic No. 450-20, as well as the unpredictability 
of E&O claims and the litigation that can flow from them, it is possible that an adverse outcome in a 
particular matter could have a material adverse effect on the Company's business, results of operations, 
financial condition or cash flow in a given quarterly or annual period.

Further, and as more fully described in Note 15 to our consolidated financial statements included under 
Part II, Item 8 of this report, we are subject to legal proceedings, regulatory investigations and other 
contingencies other than E&O claims which, if determined unfavorably to us, could have a material 
adverse effect on our business, results of operations or financial condition.

12

We cannot guarantee that we are or will be in compliance with all current and potentially 
applicable U.S. federal and state or foreign laws and regulations, and actions by regulatory 
authorities or changes in legislation and regulation in the jurisdictions in which we operate could 
have a material adverse effect on our business.

Our activities are subject to extensive regulation under the laws of the United States and its various 
states, the European Union and its member states and the other jurisdictions in which we operate. For 
example, we are subject to regulation by agencies such as the SEC in the United States and the FCA in 
the United Kingdom, state insurance regulators in the United States and self-regulatory organizations 
such as FINRA, as further described above under Part I, Item 1 - Business (Regulation) of this report. We 
are also subject to trade sanctions laws relating to countries such as Cuba, Iran, Russia, Sudan and 
Syria, and anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 
2010. We are subject to numerous other laws on matters as diverse as internal and disclosure controls 
and procedures, securities regulation, data privacy and protection, taxation, anti-trust, immigration, wage-
and-hour standards and employment and labor relations.

The U.S. and foreign laws and regulations that apply to our operations are complex, and our efforts to 
comply with these myriad laws and regulations require significant resources. In some cases, these laws 
and regulations may impose operational limitations on our business, including on the products and 
services we may offer or on the rates we may charge for our products and services. While we attempt to 
comply with all applicable laws and regulations, there can be no assurance that we, our employees, our 
consultants and our contractors and other agents are in full compliance with such laws and regulations or 
interpretations at all times, or that we will be able to comply with any future laws or regulations. If we fail 
to comply with applicable laws and regulations, including those referred to above, we may be subject to 
investigations, criminal penalties or civil remedies, including fines, injunctions, loss of an operating license 
or approval, increased scrutiny or oversight by regulatory authorities, the suspension of individual 
employees, limitations on engaging in a particular business or redress to clients. The cost of compliance 
and the consequences of non-compliance could have a material adverse effect on our business, results of 
operations and financial condition. In addition, a failure to comply with applicable laws and regulations 
could have a material adverse effect on the Company by exposing us to negative publicity and 
reputational damage or by harming our client or employee relationships.

In most jurisdictions, government regulatory authorities have the power to interpret and amend applicable 
laws and regulations, and have discretion to grant, renew and revoke the various licenses and approvals 
we need to conduct our activities. Such authorities may require the Company to incur substantial costs in 
order to comply with such laws and regulations. In some areas of our businesses, we act on the basis of 
our own or the industry's interpretations of applicable laws or regulations, which may conflict from state to 
state or country to country. In the event those interpretations eventually prove different from the 
interpretations of regulatory authorities, we may be penalized or precluded from carrying on our previous 
activities. Moreover, the laws and regulations to which we are subject may conflict among the various 
jurisdictions and countries in which we operate, which increases the likelihood of our businesses being 
non-compliant in one or more jurisdictions.

We could incur significant liability or our reputation could be damaged if our information systems 
are breached or we otherwise fail to protect client or Company data or information systems.

We rely on the efficient, uninterrupted and secure operation of complex information technology systems 
and networks to operate our business and securely process, transmit and store electronic information. 
Information technology systems are potentially vulnerable to damage or interruption from a variety of 
sources, including cyber-attacks, computer viruses and other malware, ransomware and other types of 
security breaches. Our systems are also subject to compromise from improper action by employees, 
vendors and other third parties with otherwise legitimate access to our systems. We could experience 
significant harm if our information systems are breached, or sensitive client or Company data are 
compromised. 

We are at risk of attack by a growing list of adversaries, be it state-sponsored organizations, organized 
crime, hackers or "hactivists" (activist hackers), through use of increasingly sophisticated methods of 
attack, including long-term, persistent attacks referred to as advanced persistent threats. Because the 

13

techniques used to obtain unauthorized access or sabotage systems change frequently and generally are 
not identified until they are launched against a target, we may be unable to anticipate these techniques or 
implement adequate preventative measures, resulting in potential data loss or other damage to 
information technology systems.  

As the breadth and complexity of our infrastructure continues to grow, including as a result of the use of 
mobile technologies, cloud services, social media and the increased reliance on devices connected to the 
Internet (known as the "Internet of Things"), the potential risk of security breaches and cyberattacks also 
increases. Although encryption is growing in use as a means to protect data from theft, we may not be 
able to encrypt the data across our diverse systems. Should an attacker gain access to our network using 
compromised credentials of an authorized user, we are at risk that the attacker might successfully 
leverage that access to compromise additional systems and data. Certain measures that could increase 
the security of our infrastructure, such as data encryption or deployment of multi-factor authentication, 
take significant time and resources to deploy broadly. The inability to implement, maintain and upgrade 
adequate safeguards could have a material adverse effect on our business. 

Due to the large number of systems and platforms that we operate, the increased frequency at which 
vendors issue security patches to their products and the need to test patches and, in some cases 
coordinate with clients and vendors, before they can be deployed, we are at risk that we cannot deploy 
patches in a timely manner. We are also dependent on third party vendors like cloud service providers to 
keep their systems patched in order to protect our data. If we, our clients and our vendors are unable to 
keep our systems patched in a timely manner, our systems may be breached, which could have a 
material adverse effect on our business. 

We have numerous vendors and other third parties who receive personal information from us in 
connection with the services we offer our clients. A small percentage of them have direct access to our 
systems. We are at risk of a cyber-attack involving a vendor or other third party, which could result in a 
breakdown of its data protection processes or the cyber-attackers gaining access to our infrastructure 
through the third party. To the extent that a vendor or third party suffers a cyberattack that compromises 
their operations, we could incur significant costs and possible service interruption, which could have an 
adverse effect on our business.

We have a history of making acquisitions, including 92 acquisitions in the period from 2009-2015. The 
process of integrating the information systems of the businesses we acquire is complex and exposes us 
to additional risk. For instance, we may not adequately identify weaknesses in the target’s information 
systems, either before or after the acquisition, which could affect the value we are able to derive from the 
acquisition, expose us to unexpected liabilities or make our own systems more vulnerable to a cyber-
attack. We may also be unable to integrate the systems of the businesses we acquire into our 
environment in a timely manner, which could further increase these risks until such integration takes 
place.

Our policies, procedures and technical safeguards may be insufficient to prevent or detect improper 
access to confidential, personal or proprietary information by employees, vendors or other third parties 
with otherwise legitimate access to our systems. Improper access to or disclosure of sensitive client or 
Company information could harm our reputation and subject us to liability under our contracts, as well as 
under existing or future laws, rules and regulations, resulting in increased legal and other costs and harm 
to our reputation and our business.  

We have from time to time experienced data incidents and cybersecurity breaches, such as malware 
incursions (including computer viruses and ransomware), users exceeding their data access 
authorization, employee misconduct, and incidents resulting from human error, such as loss of portable 
and other data storage devices. Like many companies, we are subject to regular phishing email 
campaigns directed at our employees that can result in malware infections and data losses. Although 
these incidents have resulted in data loss and other damages, to date, they have not had a material 
adverse effect on our business or operations. In the future, these types of incidents could result in 
confidential, personal or proprietary information being lost or stolen, including client, employee or 
company data, which could have a material adverse effect on our business. We also may be unable to 
detect an incident, assess its severity or impact, or appropriately respond in a timely manner.

14

Privacy laws are proliferating and changing frequently, at times in a manner that creates 
conflicting demands. We may not be in compliance with all applicable U.S. federal and state or 
foreign privacy and data protection laws and regulations in the jurisdictions in which we operate.

In providing services and solutions to clients, we store sensitive client or Company data, including 
personal data, in multiple jurisdictions. We leverage systems and applications that are spread all over the 
world requiring us to regularly move data across national borders. We expect these activities to increase 
in scope and complexity. As a result, we are subject to numerous laws and regulations designed to 
protect personal data, such as the national laws implementing the European Union’s Data Protection 
Directive and various U.S. federal and state laws governing the protection of health or other personally 
identifiable information. These laws and regulations are frequently changing and are becoming 
increasingly complex and sometimes conflict among the various jurisdictions and countries in which we 
provide services. For example, the European Union has just reached an agreement on a new General 
Data Protection Regulation (the GDPR) that greatly increases the jurisdictional reach of its laws and adds 
a broad array of requirements for handling personal data, such as privacy impact assessments, data 
portability and the appointment of data protection officers in some cases. Other countries are passing 
data localization laws that require data to stay within their borders. All of these evolving compliance and 
operational requirements impose significant costs that are likely to increase over time.

Unauthorized disclosure of sensitive or confidential client or Company data, whether through systems 
failure, employee negligence, fraud or misappropriation, could subject us to significant litigation, monetary 
damages, regulatory enforcement actions, fines and criminal prosecution in one or more jurisdictions. 
Under the GDPR, certain violations may trigger a fine of up to 4% of a corporation’s global annual 
revenue. Such events could also result in negative publicity and damage to our reputation, and cause us 
to lose clients, and could therefore have a material adverse effect on our results of operations. Our liability 
insurance, which includes cyber insurance, may not be sufficient in type or amount to cover us against 
claims related to security breaches, cyberattacks and other related breaches.

Financial Risks

Our pension obligations could cause the Company's financial position, earnings and cash flows 
to fluctuate.

The Company has significant pension obligations to its current and former employees, totaling 
approximately $14.8 billion, and related plan assets of approximately $14.0 billion, at December 31, 2015. 
The Company's policy for funding its tax-qualified defined benefit retirement plans is to contribute 
amounts at least sufficient to meet the funding requirements set forth by U.S. law and the laws of the non-
U.S. jurisdictions in which the Company offers defined benefit plans. In the United States, contributions to 
the tax-qualified defined benefit plans are based on ERISA guidelines. Contribution rates for non-U.S. 
plans are generally based on local funding practices and statutory requirements, which may differ from 
measurements under U.S. GAAP. In the United Kingdom, for example, contributions to defined benefit 
pension plans are based on statutory requirements and are determined through a negotiation process 
between the Company and the plans' trustee. This negotiation process is governed by U.K. pension 
regulations. Certain of the assumptions that result from the funding negotiations are different from those 
used for U.S. GAAP and currently result in a lower funded status than under U.S. GAAP.

During 2015, the Company contributed $29 million to its U.S. pension plans and $166 million to its non-
U.S. pension plans. The calculations relating to our defined benefit pension plans are complex. As 
indicated in Note 8 to our consolidated financial statements, pension plan assets and liabilities, periodic 
pension expense and future funding amounts are affected by future asset performance, the assumed 
interest rates we use to discount our pension liabilities, rates of inflation, mortality assumptions and other 
variables. Given the magnitude of our worldwide pension plans, variations in or reassessment of the 
preceding factors or potential miscalculations relating to our defined benefit pension plans could cause 
significant fluctuation from year to year in our earnings and cash flow, as well as our pension plan assets, 
liabilities and equity, and may result in increased levels of contributions to our pension plans.

15

Our results of operations could be adversely affected by macroeconomic conditions and political 
events around the world and the effects of these conditions and events on our clients' businesses 
and levels of business activity.

Macroeconomic conditions and political events around the world affect our clients' businesses and the 
markets they serve. These conditions may reduce demand for our services or depress pricing for those 
services, which could have a material adverse effect on our results of operations. Changes in 
macroeconomic and political conditions could also shift demand to services for which we do not have a 
competitive advantage, and this could negatively affect the amount of business that we are able to obtain. 
If the demand for our products and services declines as a result of macroeconomic conditions, political 
events or other factors, we may be required to restructure our business, which could adversely affect our 
ability to execute our business strategy.

Our investments, including our minority investments in other companies as well as our cash investments 
and those held in a fiduciary capacity, are subject to general credit, liquidity, counterparty, market and 
interest rate risks. These may be exacerbated by global macroeconomic conditions, market volatility and 
regulatory, financial and other difficulties affecting the companies in which we have invested or that may 
be faced by financial institution counterparties. During times of stress in the banking industry, counterparty 
risk can quickly escalate, potentially resulting in substantial trading and investment losses for corporate 
and other investors. In addition, we may incur investment losses as a result of unusual and unpredictable 
market developments, and we may continue to experience reduced investment earnings if the yields on 
investments deemed to be low risk remain at or near their current low levels. If the banking system or the 
fixed income, interest rate, credit or equity markets deteriorate, the value and liquidity of our investments 
could be adversely affected.

Our significant non-U.S. operations expose us to exchange rate fluctuations and various risks that 
could impact our business.

We are subject to exchange rate movement because some of our subsidiaries receive revenue other than 
in their functional currencies and because we must translate the financial results of our foreign 
subsidiaries into U.S. dollars. Our U.S. operations earn revenue and incur expenses primarily in U.S. 
dollars. In certain jurisdictions, however, our Risk and Insurance Services operations generate revenue in 
a number of different currencies, but expenses are almost entirely incurred in local currency. Due to 
fluctuations in foreign exchange rates, we are subject to economic exposure as well as currency 
translation exposure on the profits of our operations. Because the non-U.S. based revenue that is 
exposed to foreign exchange fluctuations is approximately 51% of total revenue, exchange rate 
movement can have a significant impact on our business, financial condition, results of operations and 
cash flow. For additional discussion, see "Market Risk and Credit Risk-Foreign Currency Risk" in Part II, 
Item 7A ("Quantitative and Qualitative Disclosures about Market Risk") of this report.

We may not be able to receive dividends or other distributions in needed amounts from our 
subsidiaries.

The Company is organized as a legal entity separate and distinct from our operating subsidiaries. 
Because we do not have significant operations of our own, we are dependent upon dividends and other 
payments from our operating subsidiaries to meet our obligations for paying principal and interest on 
outstanding debt obligations, paying dividends to stockholders, repurchasing our common stock under 
our share repurchase program and paying corporate expenses. In the event our operating subsidiaries 
are unable to pay sufficient dividends and make other payments to the Company, we may not be able to 
service our debt, pay dividends on or repurchase our common stock or meet our other obligations.

Further, the Company derives a significant portion of its revenue and operating profit from operating 
subsidiaries located outside the United States. Funds from current year’s earnings of the Company's non-
U.S. operating subsidiaries are regularly repatriated to the United States. A number of factors could arise 
that could limit our ability to repatriate funds or could make repatriation cost-prohibitive, including, but not 
limited to, the imposition of currency controls and other government restrictions on repatriation in the 
jurisdictions in which our subsidiaries operate, fluctuations in foreign exchange rates, the imposition of 
withholding and other taxes on such payments and our ability to repatriate earnings in a tax-efficient 
manner.

16

In the event we are unable to generate or repatriate cash from our operating subsidiaries for any of the 
reasons discussed above, our overall liquidity could deteriorate and our ability to finance our obligations, 
including to pay dividends on or repurchase our common stock, could be adversely affected.

Credit rating downgrades would increase our financing costs and could subject us to operational 
risk.

Currently, the Company's senior debt is rated A- by S&P and Baa1 by Moody's. The ratings from both 
S&P and Moody's currently carry a Stable outlook.

If we need to raise capital in the future (for example, in order to fund maturing debt obligations or finance 
acquisitions or other initiatives), credit rating downgrades would increase our financing costs, and could 
limit our access to financing sources. Further, we believe that a downgrade to a rating below investment-
grade could result in greater operational risks through increased operating costs and increased 
competitive pressures.

Our quarterly revenues and profitability may fluctuate significantly.

Quarterly variations in revenues and operating results may occur due to several factors. These include:

• 

• 

• 

• 

• 

the significance of client engagements commenced and completed during a quarter;

the possibility that clients may decide to delay or terminate a current or anticipated 
project as a result of factors unrelated to our work product or progress;

fluctuations in hiring and utilization rates and clients' ability to terminate engagements 
without penalty;

seasonality due to the impact of regulatory deadlines, policy renewals and other timing 
factors to which our clients are subject;

the success of our acquisitions or investments;

•  macroeconomic factors such as changes in foreign exchange rates, interest rates and 

global securities markets, particularly in the case of Mercer, where fees in its investments 
business and certain other business lines are derived from the value of assets under 
management or administration; and

• 

general economic conditions, since results of operations are directly affected by the 
levels of business activity of our clients, which in turn are affected by the level of 
economic activity in the industries and markets that they serve.

A significant portion of our total operating expenses is relatively fixed in the short term. Therefore, a 
variation in the number of client assignments or in the timing of the initiation or the completion of client 
assignments can cause significant variations in quarterly operating results for these businesses.

If we are unable to collect our receivables, our results of operations and cash flows could be 
adversely affected.

Our business depends on our ability to successfully obtain payment from our clients of the amounts they 
owe us for the work we perform. Accounts receivable typically total about one-quarter of our total annual 
revenues. In most cases, we bill and collect on relatively short cycles. There is no guarantee that we will 
accurately assess the creditworthiness of our clients. Macroeconomic conditions could result in financial 
difficulties for our clients, which could cause clients to delay payments to us, request modifications to their 
payment arrangements that could increase our receivables balance or default on their payment 
obligations to us. Timely collection of client balances also depends on our ability to complete our 
contractual commitments and bill and collect our contracted revenues. If we are unable to meet our 
contractual requirements, we might experience delays in collection of, or be unable to collect, our client 
balances, and if this occurs, our results of operations and cash flows could be adversely affected. In 
addition, if we experience an increase in the time it takes to bill and collect for our services, our cash 
flows could be adversely affected.

17

Market perceptions concerning the instability of the Euro could adversely affect the Company's 
operating results as well as the value of the Company's Euro-denominated assets.

Concerns persist regarding the ability of certain Eurozone countries to service their debt obligations. As a 
result, a number of these countries have undertaken a variety of actions, such as cutting spending and 
raising taxes, designed to ease their future debt burdens. A potential consequence may be stagnant 
growth, or even recession, in the Eurozone economies and beyond. Any of these developments could 
lead to further contraction in the Eurozone economies, adversely affecting our operating results in the 
region. The Company may also face increased credit risk as our clients and financial institution 
counterparties in the region find themselves with reduced resources to meet their obligations. Finally, the 
value of the Company's assets held in the Eurozone, including cash holdings, will decline if the currency 
devalues. 

Global Operations

We are exposed to multiple risks associated with the global nature of our operations.

We do business worldwide. In 2015, 51% of the Company's total revenue was generated from operations 
outside the United States, and over one-half of our employees were located outside the United States. 
We expect to expand our non-U.S. operations further.

The geographic breadth of our activities subjects us to significant legal, economic, operational, market, 
compliance and reputational risks. These include, among others, risks relating to:

• 

• 

economic and political conditions in the countries in which we operate;

unexpected increases in taxes or changes in U.S. or foreign tax laws or rulings; 

•  withholding or other taxes that foreign governments may impose on the payment of 

dividends or other remittances to us from our non-U.S. subsidiaries;

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

potential transfer pricing-related tax exposures that may result from the allocation of U.S.-
based costs that benefit our non-U.S. businesses;

potential conflicts of interest that may arise as we expand the scope of our businesses 
and our client base;

international hostilities, terrorist activities, natural disasters and infrastructure disruptions;

local investment or other financial restrictions that foreign governments may impose;

potential costs and difficulties in complying with a wide variety of foreign laws and 
regulations (including tax systems) administered by foreign government agencies, some 
of which may conflict with U.S. or other sources of law; 

potential costs and difficulties in complying, or monitoring compliance, with foreign and 
U.S. laws and regulations that are applicable to our operations abroad, including trade 
sanctions laws relating to countries such as Cuba, Iran, Russia, Sudan and Syria and 
anti-corruption laws such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery 
Act 2010;

limitations or restrictions that foreign or U.S. governments and regulators may impose on 
the products or services we sell or the methods by which we sell our products and 
services;

limitations that foreign governments may impose on the conversion of currency or the 
payment of dividends or other remittances to us from our non-U.S. subsidiaries;

the length of payment cycles and potential difficulties in collecting accounts receivable;

engaging and relying on third parties to perform services on behalf of the Company; and

potential difficulties in monitoring employees in geographically dispersed locations.

18

Our inability to successfully recover should we experience a disaster or other business continuity 
problem could cause material financial loss, loss of human capital, regulatory actions, 
reputational harm or legal liability.

Should we experience a local or regional disaster or other business continuity problem, such as an 
earthquake, hurricane, flood, terrorist attack, pandemic, security breach, cyber attack, power loss, 
telecommunications failure or other natural or man-made disaster, our ability to continue to operate will 
depend, in part, on the availability of our personnel, our office facilities and the proper functioning of our 
computer, telecommunication and other related systems and operations. In such an event, we could 
experience operational challenges that could have a material adverse effect on our business.

Our operations depend upon our ability to protect our technology infrastructure against damage from 
events that could have a significant disruptive effect. We could potentially lose client or Company data or 
experience material adverse interruptions to our operations or delivery of services to our clients in a 
disaster recovery scenario. In particular, a cyber-attack on us or a key vendor or supplier could result in a 
significant and extended disruption in the functioning of our information technology systems or operations, 
requiring us to incur significant expense to address and remediate or otherwise resolve such issues. An 
extended service outage may result in the loss of clients and a decline in our revenues. 

We regularly assess and take steps to improve our existing business continuity plans and key 
management succession. However, a disaster or other continuity event on a significant scale or affecting 
certain of our key operating areas within or across regions, or our inability to successfully recover from 
such an event, could materially interrupt our business operations and result in material financial loss, loss 
of human capital, regulatory actions, reputational harm, damaged client relationships and legal liability.

Competitive Risks

Each of the Company's businesses operates in a highly competitive environment. If we fail to 
compete effectively against our competitors, some of which have lower effective tax rates, our 
business, results of operations and financial condition will be impacted adversely.

As a global professional services firm, the Company faces acute and continuous competition in each of its 
operating segments. Our ability to compete successfully depends on a variety of factors, including the 
quality and expertise of our colleagues, our geographic reach, the sophistication and quality of our 
services, our pricing relative to competitors, our customers' ability to self-insure or use internal resources 
instead of consultants and our ability to respond to changes in client demand and industry conditions.  
Some of our competitors may have greater financial resources, or may be better positioned to respond to 
technological and other changes in the industries we serve, and they may be able to compete more 
effectively. If we are unable to respond successfully to the competition we face, our business, results of 
operations and financial condition will be adversely impacted.

In addition, given the global breadth of our operations, the Company derives a significant portion of its 
revenue and operating profit from operating subsidiaries located outside the United States.  Funds from 
the Company's non-U.S. operating subsidiaries are regularly repatriated to the United States out of 
annual earnings to pay dividends to stockholders, fund share repurchases and for other corporate 
purposes. The Company's consolidated tax rate is higher than a number of its key competitors that are 
domiciled outside the United States where corporate tax rates are lower than the U.S. statutory tax rate. 
The higher consolidated tax rate at which our earnings are taxed could have an adverse impact on our 
ability to compete with a number of our competitors.

In our Risk and Insurance Services segment, in addition to the challenges posed by capital market 
alternatives to traditional insurance and reinsurance, we compete intensely against a wide range of other 
insurance and reinsurance brokerage firms that operate on a global, regional, national or local scale for 
both client business and employee talent. We compete as well with insurance and reinsurance companies 
that market and service their insurance products without the assistance of brokers or other market 
intermediaries, and with various other companies that provide risk-related services or alternatives to 
traditional brokerage services. This competition is intensified by an industry trend toward a “syndicated” 
or “distributed” approach to the purchase of insurance and reinsurance brokerage services, whereby a 
client engages multiple brokers to service different portions of the client's account.

19

In our Consulting segment, we compete for business and employee talent with numerous consulting firms 
and organizations affiliated with accounting, information systems, technology and financial services firms 
around the world. Through these affiliations, such competitors may be able to offer more comprehensive 
products and services to potential clients, which may give them a competitive advantage.

The loss of key professionals could hurt our ability to retain existing client revenues and generate 
revenues from new business.

Across all of our businesses, our colleagues are critical to developing and retaining the client 
relationships performing the service on which our revenues depend. It is therefore important for us to 
retain significant revenue-producing employees and the key managerial and other professionals who 
support them. We face numerous challenges in this regard, including the intense competition for talent in 
all of our businesses and the general mobility of professionals in our businesses.

Losing employees who manage or support substantial client relationships or possess substantial 
experience or expertise could adversely affect our ability to secure and complete client engagements, 
which could adversely affect our results of operations. And, subject to applicable restrictive covenants, if 
any of our key professionals were to join an existing competitor or form a competing company, some of 
our clients could choose to use the services of that competitor instead of our services.

Our businesses face rapid technological changes and our failure to adequately anticipate or 
respond to these changes or to successfully implement strategic initiatives to address them could 
adversely affect our business and results of operations.

To remain competitive in many of our business areas, we must anticipate and respond effectively to the 
threat of digital disruption and other technological change. We must also identify relevant technologies 
and methodologies and integrate them into our product and service offerings. We may not be able to do 
this effectively. We have a number of strategic initiatives involving investments in technology systems and 
infrastructure to support our growth strategy. In addition to new platforms and systems, we are deploying 
new processes and many of our colleagues across the business are changing the way they perform 
certain roles to capture efficiencies. In some cases, we depend on key vendors and partners to provide 
technology and other support for our strategic initiatives. If these vendors or partners fail to perform their 
obligations or otherwise cease to work with us, our ability to execute on our strategic initiatives could be 
adversely affected. If we do not keep up with technological changes or execute well on our strategic 
initiatives, our business and results of operations could be adversely impacted.

Consolidation in the industries we serve could adversely affect our business.

Companies in the industries that we serve may seek to achieve economies of scale and other synergies 
by combining with or acquiring other companies. If two or more of our current clients merge or consolidate 
and combine their operations, it may decrease the amount of work that we perform for these clients. If 
one of our current clients merges or consolidates with a company that relies on another provider for its 
services, we may lose work from that client or lose the opportunity to gain additional work. Any of these or 
similar possible results of industry consolidation could adversely affect our business. Guy Carpenter is 
especially susceptible to this risk given the limited number of insurance company clients and reinsurers in 
the marketplace.

Acquisitions and Dispositions

We face risks when we acquire and dispose of businesses.

We have a history of making acquisitions, including a total of 92 acquisitions in the period 2009-2015 for 
aggregate purchase consideration of $4.2 billion. We expect that acquisitions will continue to be a key 
part of our business strategy. Our success in this regard will depend on our ability to identify and compete 
for appropriate acquisition candidates and to complete with favorable results the transactions we decide 
to pursue.

While we intend that our acquisitions will improve our competitiveness and profitability, we cannot be 
certain that our past or future acquisitions will be accretive to earnings or otherwise meet our operational 
or strategic expectations. Acquisitions involve special risks, including accounting, regulatory, compliance, 
information technology or human resources issues that could arise in connection with, or as a result of, 

20

the acquisition of the acquired company; the assumption of unanticipated liabilities and contingencies; 
difficulties in integrating acquired businesses; and the inability of acquired businesses to achieve the 
levels of revenue, profit or productivity we anticipate or otherwise perform as we expect. In addition, if in 
the future, the performance of our reporting units or an acquired business varies from our projections or 
assumptions, or estimates about future profitability of our reporting units or an acquired business change, 
the estimated fair value of our reporting units or an acquired business could change materially and could 
result in an impairment of goodwill and other acquisition-related intangible assets recorded on our 
balance sheet or in adjustments in contingent payment amounts. As of December 31, 2015, the 
Company's consolidated balance sheet reflected $8.9 billion of goodwill and intangible assets, 
representing approximately 49% of the Company's total consolidated assets and allocated by reporting 
segment as follows: Risk and Insurance Services, $6.5 billion and Consulting, $2.4 billion. Given the 
significant size of the Company's goodwill and intangible assets, an impairment could have a material 
adverse effect on our results of operations in any given period.

When we dispose of businesses, we are subject to the risk, contractually agreed or otherwise, that we will 
continue to be subject to the liabilities of that business after its disposition. For example, as described in 
Note 15 to our consolidated financial statements included under Part II, Item 8 of this report, we have 
retained certain contingent litigation liabilities relating to our disposition of Kroll.  

RISKS RELATING TO OUR RISK AND INSURANCE SERVICES SEGMENT

Our Risk and Insurance Services segment, conducted through Marsh and Guy Carpenter, represented 
53% of the Company's total revenue in 2015. Our business in this segment is subject to particular risks.

Results in our Risk and Insurance Services segment may be adversely affected by a general 
decline in economic activity.

Demand for many types of insurance and reinsurance generally rises or falls as economic growth 
expands or slows. This dynamic affects the level of commissions and fees generated by Marsh and Guy 
Carpenter. To the extent our clients become adversely affected by declining business conditions, they 
may choose to limit their purchases of insurance and reinsurance coverage, as applicable, which would 
inhibit our ability to generate commission revenue. Also, the insurance they seek to obtain through us 
may be impacted by changes in their assets, property values, sales or number of employees, which may 
reduce our commission revenue, and they may decide not to purchase our risk advisory services, which 
would inhibit our ability to generate fee revenue. Moreover, insolvencies and combinations associated 
with an economic downturn, especially insolvencies and combinations in the insurance industry, could 
adversely affect our brokerage business through the loss of clients or by hampering our ability to place 
insurance and reinsurance business. Guy Carpenter is especially susceptible to this risk given the limited 
number of insurance company clients and reinsurers in the market place.

Allegations of conflicts of interest, adverse legal developments and future regulations concerning  
compensation we receive from insurers could have a material adverse effect on Marsh’s business, 
results of operations and financial condition.

The method by which insurance intermediaries are compensated has received substantial scrutiny from 
regulators in the past because of the potential for conflicts of interest. The potential for conflicts of interest 
arises when an intermediary is compensated by two parties in connection with the same or similar 
transactions. The vast majority of the compensation that Marsh receives is in the form of retail 
commissions and fees that are paid by the client or paid from premium that is paid by the client. The 
amount of compensation that we receive from insurance companies, separate from retail commissions 
and fees, has increased significantly in the last several years, both organically and through acquisition. 
This compensation includes payment for, among other things (i) consulting and analytics services 
provided to insurers and (ii) administrative and other services provided to or on behalf of insurers 
(including services relating to the administration and management of quota shares, panels and other 
facilities in which insurers participate). It also takes the form of contingent commission, which is paid by 
insurers based on the attainment of specified goals relating to Marsh's placements, particularly at Marsh 
& McLennan Agency and in parts of Marsh's international operations. Future changes in the regulatory 
environment may impact our ability to collect these revenue streams. In addition, these revenues present 
potential regulatory, litigation and reputational risks that may arise from alleged conflicts of interest or 

21

allegations under antitrust, competition and other laws. Adverse regulatory, legal or other developments 
regarding these revenues could have a material adverse effect on our business, results of operations or 
financial condition, expose us to negative publicity and reputational damage and harm our client, insurer 
or other relationships.

Volatility or declines in premiums and other market trends may significantly impede our ability to 
improve revenues and profitability.

A significant portion of our Risk and Insurance Services revenue consists of commissions paid to us out 
of the premiums that insurers and reinsurers charge our clients for coverage. Our revenues and 
profitability are subject to change to the extent that premium rates fluctuate or trend in a particular 
direction. The potential for changes in premium rates is significant, due to the general phenomenon of 
pricing cyclicality in the commercial insurance and reinsurance markets.

In addition to movements in premium rates, our ability to generate premium-based commission revenue 
may be challenged by the growing availability of alternative methods for clients to meet their risk-
protection needs. This trend includes a greater willingness on the part of corporations to "self-insure," the 
use of so-called "captive" insurers, and the advent of capital markets-based solutions to traditional 
insurance and reinsurance needs. Further, the profitability of our Risk and Insurances Services segment 
depends in part on our ability to be compensated, not only for insurance and reinsurance transactions, 
but also for the increasing analytical services and advice that we provide. If we are unable to achieve and 
maintain adequate billing rates for all of our services, our margins and profitability could decline.

RISKS RELATING TO OUR CONSULTING SEGMENT

Our Consulting segment, conducted through Mercer and Oliver Wyman Group, represented 47% of our 
total revenue in 2015. Our businesses in this segment are subject to particular risks.

Revenues for our services may decline for various reasons, including as a result of changes in 
economic conditions, the value of equity, debt and other asset markets, our clients’ or an 
industry's financial condition or government regulation.

Global economic conditions over the past several years have negatively affected businesses and financial 
institutions. Many of our clients, including financial institutions, corporations, government entities and 
pension plans, have been reducing expenses, including amounts spent on consulting services. The 
evolving needs and financial circumstances of our clients may reduce demand for our services and our 
revenues and profitability. If the economy or markets in which we operate experience continued weakness 
at current levels or deteriorate further, our business, financial condition and results of operations could be 
materially and adversely affected.

In addition, some segments of Mercer's investments business generate fees based upon the value of the 
clients’ assets under management or advisement. Changes in the value of equity, debt, currency, real 
estate, commodities or other asset classes could cause the value of assets under management or 
advisement, and the fees received by Mercer, to decline. Such changes could also cause clients to 
withdraw funds from Mercer’s investment business in favor of other asset management strategies.  In 
either case, our business, financial condition and results of operations could be materially and adversely 
affected.

Demand for many of Mercer's benefits services is affected by government regulation and tax rules, which 
drive our clients' needs for benefits-related services. Significant changes in government regulations 
affecting the value, use or delivery of benefits and human resources programs, including changes in 
regulations relating to health and welfare plans, defined contribution plans or defined benefit plans, may 
adversely affect the demand for or profitability of Mercer's services.

Factors affecting defined benefit pension plans and the services we provide relating to those 
plans could adversely affect Mercer.

Mercer currently provides corporate, multi-employer and public clients with actuarial, consulting and 
administration services relating to defined benefit pension plans. The nature of our work is complex. Our 
actuarial services involve numerous assumptions and estimates regarding future events, including 
interest rates used to discount future liabilities, estimated rates of return for a plan's assets, healthcare 
cost trends, salary projections and participants' life expectancies. Our consulting services involve the 

22

drafting and interpretation of trust deeds and other complex documentation governing pension plans. Our 
administration services include calculating benefits within complicated pension plan structures. Clients 
dissatisfied with our services have brought, and may bring, significant claims against us, particularly in the 
United States and the United Kingdom. In addition, a number of Mercer's clients have frozen or curtailed 
their defined benefit plans and have moved to defined contribution plans resulting in reduced revenue for 
Mercer's retirement business. These developments could adversely affect Mercer's business and 
operating results.         

Mercer’s investment business is subject to a number of risks, including risks related to third-party 
investment managers, operational risk, conflicts of interest, asset performance and regulatory 
compliance, that, if realized, could result in significant damage to our business.

Mercer’s investment business provides clients with investment consulting and investment management 
(referred to as "delegated solutions") services. In the investment consulting business, clients make and 
implement their own investment policy decisions based upon advice provided by Mercer. In its delegated 
solutions business, Mercer implements the client’s investment policy by engaging and overseeing 
independent investment managers who determine which securities to buy and sell (typically through the 
client’s investment in Mercer's "manager of managers" funds).  

Mercer’s investment business is subject to a number of risks, including risks related to third-parties, our 
operations, conflicts of interest, asset performance and regulatory compliance, which could arise in 
connection with these offerings. For example, Mercer’s due diligence on an investment manager may fail 
to uncover material deficiencies or fraud that could result in investment losses to a client. There is a risk 
that Mercer will fail to properly implement a client’s investment policy, which could cause an incorrect or 
untimely allocation of client assets among investment managers or strategies. Mercer may also be 
perceived as recommending certain investment managers to clients, or offering delegated solutions to an 
investment consulting client, solely to enhance its own compensation. Asset classes may perform poorly, 
or investment managers may underperform their benchmarks, due to poor market performance, 
negligence or other reasons, resulting in poor returns or loss of client capital. These risks, if realized, 
could result in significant liability and damage our business.

Our profitability may decline if we are unable to achieve or maintain adequate utilization and 
pricing rates for our consultants.

The profitability of our Consulting businesses depends in part on ensuring that our consultants maintain 
adequate utilization rates (i.e., the percentage of our consultants' working hours devoted to billable 
activities). Our utilization rates are affected by a number of factors, including:

• 

• 

• 

• 

• 

• 

• 

• 

• 

our ability to transition consultants promptly from completed projects to new assignments, 
and to engage newly-hired consultants quickly in revenue-generating activities;

our ability to continually secure new business engagements, particularly because a 
portion of our work is project-based rather than recurring in nature;

our ability to forecast demand for our services and thereby maintain appropriate 
headcount in each of our geographies and workforces;

our ability to manage attrition;

unanticipated changes in the scope of client engagements;

the potential for conflicts of interest that might require us to decline client engagements 
that we otherwise would have accepted;

our need to devote time and resources to sales, training, professional development and 
other non-billable activities;

the potential disruptive impact of acquisitions and dispositions; and

general economic conditions.

If the utilization rate for our consulting professionals declines, our profit margin and profitability could 
decline.

23

In addition, the profitability of our Consulting businesses depends in part on the prices we are able to 
charge for our services. The prices we charge are affected by a number of factors, including:

• 

clients' perception of our ability to add value through our services;

•  market demand for the services we provide;

• 

• 

• 

• 

our ability to develop new services and the introduction of new services by competitors;

the pricing policies of our competitors;

the extent to which our clients develop in-house or other capabilities to perform the 
services that they might otherwise purchase from us; and

general economic conditions.

If we are unable to achieve and maintain adequate billing rates for our services, our profit margin and 
profitability could decline.

Item 1B.    Unresolved Staff Comments.

There are no unresolved comments to be reported pursuant to Item 1B.

Item 2.      Properties.

Marsh & McLennan Companies maintains its corporate headquarters in New York City. We also maintain 
other offices around the world, primarily in leased space. In certain circumstances we may have space 
that we sublet to third parties, depending upon our needs in particular locations.

Marsh & McLennan Companies and certain of its subsidiaries own, directly and indirectly through special 
purpose subsidiaries, a 58% condominium interest covering approximately 900,000 square feet of office 
space in a 44-story building in New York City. This real estate serves as the Company's headquarters and 
is occupied primarily by the Company and its subsidiaries for general corporate use. The remaining 
condominium interests in this property are owned by unaffiliated third parties. The Company’s owned 
interest is financed by a 30-year loan that is non-recourse to the Company (except in the event of certain 
prohibited actions) and secured by a first mortgage lien on the condominium interest and a first priority 
assignment of leases and rents. In the event (1) the Company is downgraded below B (stable outlook) by 
S&P or Fitch or B2 (stable outlook) by Moody’s or (2) an event of default under the loan has occurred and 
is continuing, the Company would be obligated to pay rent for the entire occupancy of the mortgaged 
property, which would, in effect, pay the mortgage.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations 

General

Marsh & McLennan Companies, Inc. and subsidiaries (the "Company") is a global professional services 
firm offering clients advice and solutions in risk, strategy and people. It is the parent company of a number 
of leading risk experts and specialty consultants, including: Marsh, the insurance broker, intermediary and 
risk advisor; Guy Carpenter, the risk and reinsurance specialist; Mercer, the provider of HR and related 
financial advice and services; and Oliver Wyman Group, the management, economic and brand 
consultancy. With approximately 60,000 employees worldwide and annual revenue of nearly $13 billion, 
the Company provides analysis, advice and transactional capabilities to clients in more than 130 
countries.

The Company conducts business through two segments:

•  Risk and Insurance Services includes risk management activities (risk advice, risk transfer and 
risk control and mitigation solutions) as well as insurance and reinsurance broking and services. 
We conduct business in this segment through Marsh and Guy Carpenter.

•  Consulting includes Health, Retirement, Talent and Investments consulting services and 

products, and specialized management, economic and brand consulting services. We conduct 
business in this segment through Mercer and Oliver Wyman Group.

We describe the primary sources of revenue and categories of expense for each segment below, in our 
discussion of segment financial results. A reconciliation of segment operating income to total operating 
income is included in Note 16 to the consolidated financial statements included in Part II, Item 8 in this 
report. The accounting policies used for each segment are the same as those used for the consolidated 
financial statements.

This Management's Discussion & Analysis ("MD&A") contains forward-looking statements as that term is 
defined in the Private Securities Litigation Reform Act of 1995. See "Information Concerning Forward-
Looking Statements" at the outset of this report.

Consolidated operating income increased 5% to $2.4 billion in 2015 compared with $2.3 billion in 2014, 
reflecting the combined impact of a slight decrease in revenue and a 2% decrease in expenses as 
compared to the prior year. The Company achieved this growth despite significant foreign exchange 
headwinds, caused by the strengthened U.S. dollar, which had the effect of reducing the translated value 
of the Company’s foreign earnings.

Diluted net income per share from continuing operations was $2.98, compared to $2.61 last year, 
reflecting a $160 million increase in net income as well as a 3% decrease in the average number of 
diluted shares outstanding as compared to the same period last year. Shares issued related to the vesting 
of share awards and exercise of employee stock options were more than offset by share repurchases 
over the past four quarters.

Risk and Insurance Services operating income increased $30 million or 2% in 2015 compared with 2014. 
Revenue decreased 1%, but increased 3% on an underlying basis, to $6.9 billion in 2015, reflecting 
underlying revenue growth of 3% at Marsh and 2% at Guy Carpenter, while expenses decreased 2%, but 
increased 2% on an underlying basis. 

Consulting operating income increased $80 million or 8% to $1.1 billion in 2015 compared with 2014, 
reflecting flat revenue, but an increase of 5% on an underlying basis. Expense decreased 1%, but 
increased 4% on an underlying basis. Mercer and Oliver Wyman recorded underlying revenue growth of 
4% and 7%, respectively, in 2015 as compared to 2014. The operating income and revenue in 2015 
include a pre-tax gain of $37 million from the sale of Mercer's U.S. defined contribution recordkeeping 
business.

Consolidated operating income increased 11% to $2.3 billion in 2014 compared with $2.1 billion in 2013.  
This reflects the combined impact of a 6% increase in revenue and a 5% increase in expense.

Risk and Insurance Services operating income increased $88 million or 6% in 2014 compared with 2013. 
Revenue increased 5%, or 3% on an underlying basis, to $6.9 billion in 2014, reflecting underlying 
revenue growth of 4% at Marsh and 2% at Guy Carpenter, while expenses increased 5%, or 3% on an 
underlying basis. 

Consulting operating income increased $151 million or 18% to $996 million in 2014 compared with 2013, 
reflecting a 6% increase in revenue and a 4% increase in expense. Mercer and Oliver Wyman recorded 
underlying revenue growth of 3% and 15%, respectively, in 2014 as compared to 2013.

The Company recorded expenses related to the early extinguishment of debt of $137 million in 2014 and 
$24 million in 2013.

Consolidated net income attributable to the Company was $1.6 billion in 2015, compared with $1.5 billion 
in 2014 and $1.4 billion in 2013.

Consolidated Revenue and Expense
Because the Company conducts business in many countries, foreign exchange rate movements may 
impact period-to-period comparisons of revenue. Similarly, the revenue impact of acquisitions and 
dispositions may affect period-to-period comparisons of revenue. Underlying revenue measures the 
change in revenue from one period to another by isolating these impacts. The impact of foreign currency 
exchange fluctuations, acquisitions and dispositions, including transfers among businesses and other 
items, on the Company’s operating revenues is as follows:

Revenue

Consolidated revenue was $12.9 billion in 2015, a slight decrease from last year, but an increase of 4% 
on an underlying basis. Revenue in the Risk and Insurance Services segment decreased 1% in 2015 
compared with 2014, but increased 3% on an underlying basis. Revenue increased 3% and 2% on an 
underlying basis at Marsh and Guy Carpenter, respectively, as compared to 2014. The Consulting 

30

  
  
  
  
segment's revenue was flat compared to 2014, but increased 5% on an underlying basis. Mercer and 
Oliver Wyman's revenue increased 4% and 7% on an underlying basis, respectively, compared to 2014. 

Consolidated revenue of $13 billion in 2014 increased 6%, or 5% on an underlying basis, compared with 
$12.3 billion in 2013. Revenue in the Risk and Insurance Services segment increased 5% in 2014 
compared with 2013, or 3% on an underlying basis, with underlying revenue growth of 4% at Marsh and 
2% at Guy Carpenter. The Consulting segment's revenue increased 6% on both a reported and 
underlying basis. On an underlying basis, Mercer's revenue was up 3% in 2014 compared with 2013, 
while revenue of the Oliver Wyman Group increased 15%.

Operating Expense

Consolidated operating expenses decreased 2% in 2015 compared with the same period in 2014, but 
increased 3% on an underlying basis. The increase in underlying expenses primarily reflects higher base 
salary, bonus, and higher defined benefit and defined contribution plan costs ("retirement benefit costs"), 
partly offset by the impact of the net benefit from the termination of the Company's post-65 retiree medical 
reimbursement plan in the U.S. (the "RRA Plan").

Consolidated operating expenses increased 5% in 2014 compared with the same period in 2013 and 4% 
on an underlying basis. The increase in underlying expenses primarily reflects higher incentive 
compensation, facilities and software amortization costs, partly offset by lower pension costs.

Risk and Insurance Services

In the Risk and Insurance Services segment, the Company’s subsidiaries and other affiliated entities act 
as brokers, agents or consultants for insureds, insurance underwriters and other brokers in the areas of 
risk management, insurance broking and insurance program management services, primarily under the 
name of Marsh; and engage in reinsurance broking, catastrophe and financial modeling services and 
related advisory functions, primarily under the name of Guy Carpenter.

Marsh and Guy Carpenter are compensated for brokerage and consulting services primarily through fees 
paid by clients and/or commissions paid out of premiums charged by insurance and reinsurance 
companies. Commission rates vary in amount depending upon the type of insurance or reinsurance 
coverage provided, the particular insurer or reinsurer, the capacity in which the broker acts and 
negotiations with clients. Revenues can be affected by premium rate levels in the insurance/reinsurance 
markets, the amount of risk retained by insurance and reinsurance clients themselves and by the value of 
the risks that have been insured since commission-based compensation is frequently related to the 
premiums paid by insureds/reinsureds. In many cases, fee compensation may be negotiated in advance, 
based on the type of risk, coverage required, and service provided by the Company and ultimately placed 
into the insurance market or retained by the client. The trends and comparisons of revenue from one 
period to the next can be affected by changes in premium rate levels, fluctuations in client risk retention, 
and increases or decreases in the value of risks that have been insured, as well as new and lost 
business, and the volume of business from new and existing clients. 

Marsh also receives compensation from insurance companies. This compensation includes, among other 
things, payment for consulting and analytics services provided to insurers; administrative and other 
services provided to or on behalf of insurers (including services relating to the administration and 
management of quota share, panels and other facilities in which insurers participate); and contingent 
commissions. Marsh and Guy Carpenter receive interest income on certain funds (such as premiums and 
claims proceeds) held in a fiduciary capacity for others. The investment of fiduciary funds is regulated by 
state and other insurance authorities. These regulations typically require segregation of fiduciary funds 
and limit the types of investments that may be made with them. Interest income from these investments 
varies depending on the amount of funds invested and applicable interest rates, both of which vary from 
time to time. For presentation purposes, fiduciary interest is segregated from the other revenues of Marsh 
and Guy Carpenter and separately presented within the segment, as shown in the revenue by segments 
charts earlier in this MD&A.

Revenue in the Risk and Insurance Services segment decreased 1%, but increased 3% on an underlying 
basis, in 2015 compared with 2014.  

In Marsh, revenue of $5.7 billion, was essentially flat on a reported basis in 2015 as compared to 2014, 
reflecting a 3% increase on an underlying basis and a 3% increase from acquisitions, offset by a 7% 
decrease resulting from the impact of foreign currency translation. The underlying revenue increase 
reflects growth in all major geographies. International operations had underlying revenue growth of 3% 
reflecting increases of 8% in Latin America, 2% in Asia Pacific and 2% in EMEA, while U.S./Canada 
increased 3%.

Guy Carpenter’s revenue decreased 3% to $1.1 billion in 2015 compared with 2014, but increased 2% on 
an underlying basis.

Fiduciary interest income was $21 million in 2015 compared to $24 million in 2014 due to lower average 
invested funds combined with lower interest rates.

The Risk and Insurance Services segment completed thirteen acquisitions during 2015. Acquisition 
details can be found in Note 4 to the consolidated financial statements.

Revenue in the Risk and Insurance Services segment increased 5%, or 3% on an underlying basis, in 
2014 compared with 2013.

In Marsh, revenue grew to $5.8 billion or 6% in 2014 as compared to 2013, reflecting a 4% increase on 
an underlying basis and a 3% increase from acquisitions, partly offset by a 1% decrease resulting from 
the impact of foreign currency translation. The underlying revenue increase reflects growth in all major 
geographies driven by strong new business, particularly in countries such as the U.S., Canada, and the 
U.K., as well as in Africa. International operations had underlying revenue growth of 5% reflecting 
increases of 10% in Latin America, 7% in Asia Pacific and 3% in EMEA, while U.S./Canada increased 
3%.  

Guy Carpenter’s revenue increased 2% to $1.2 billion in 2014 compared with 2013 on both a reported 
and an underlying basis, reflecting growth across the U.S., U.K. Facultative, Asia and Global Specialties 
such as Aviation and Marine.

Fiduciary interest income was $24 million in 2014 compared to $27 million in 2013 due to lower average 
invested funds combined with lower interest rates.

The Risk and Insurance segment completed fifteen acquisitions during 2014.

Expense

Expenses in the Risk and Insurance Services segment decreased 2% on a reported basis, but increased 
2% on an underlying basis, in 2015 compared with 2014. The impact of foreign currency translation 
reduced expenses by 7%, partly offset by a 3% increase related to acquisitions. The increase in 
underlying expenses reflects higher base salaries, incentive compensation and retirement benefit costs, 
higher amortization of intangible assets and charges for adjustments to acquisition-related contingent 
consideration liabilities, partly offset by the impact of the net benefit from the termination of the RRA plan.

Expenses in the Risk and Insurance Services segment increased 5% on a reported basis and 3% on an 
underlying basis in 2014 compared with 2013. The increase in expenses on an underlying basis is 

32

primarily due to higher base salaries, incentive compensation, facilities and intangible asset amortization 
expenses, partly offset by lower defined benefit pension costs.

Consulting

The Company conducts business in its Consulting segment through two main business groups. Mercer 
provides consulting expertise, advice, services and solutions in the areas of health, retirement, talent and 
investments. Oliver Wyman Group provides specialized management, economic and brand consulting 
services.

The major component of revenue in the Consulting business is fees paid by clients for advice and 
services. Mercer, principally through its health line of business, also earns revenue in the form of 
commissions received from insurance companies for the placement of group (and occasionally individual) 
insurance contracts, primarily life, health and accident coverages. Revenue for Mercer’s investment 
management business and certain of Mercer’s defined contribution administration services consists 
principally of fees based on assets under management and/or administration.

Revenue in the Consulting segment is affected by, among other things, global economic conditions, 
including changes in clients’ particular industries and markets. Revenue is also affected by competition 
due to the introduction of new products and services, broad trends in employee demographics, including 
levels of employment, the effect of government policies and regulations, and fluctuations in interest and 
foreign exchange rates. Revenues from the provision of investment management services and retirement 
trust and administrative services are significantly affected by the level of assets under management and 
securities market performance. 

Reimbursable expenses incurred by professional staff in the generation of revenue and sub-advisory fees 
incurred by the majority of funds are included on a gross basis in the investment management business in 
revenue and the related expenses are included in other operating expenses.

Consulting revenue in 2015, was essentially flat compared to 2014, reflecting a 5% increase on an 
underlying basis and a 2% increase related to acquisitions, offset by a 7% decrease from the impact of 
foreign currency translation. Mercer’s revenue was $4.3 billion in 2015, a decrease of 1%, but an increase 
of 4% on an underlying basis. The year over year revenue change also reflects an increase of 2% from 
acquisitions/dispositions, offset by a decrease of 7% from the impact of foreign currency translation. 
Mercer's revenue includes a $37 million gain from the disposal of its U.S. defined contribution 
recordkeeping business, and is reflected in the 2% impact from acquisitions/dispositions. The underlying 
revenue growth reflects an increase in Investments of 7%, Health of 6% and Talent of 5%, while 
Retirement remained flat. Oliver Wyman’s revenue increased 3% in 2015 compared to 2014, reflecting an 
increase of 7% on an underlying basis and a 2% increase from acquisitions, partly offset by a decrease of 
6% from the impact of foreign currency translation.

The Consulting segment completed eight acquisitions during 2015. Acquisition details can be found in 
Note 4 to the consolidated financial statements.

Consulting revenue in 2014 increased 6% on both a reported and underlying basis as compared to 2013. 
Mercer’s revenue was $4.4 billion in 2014, an increase of 3% on both a reported and underlying basis, 
partly offset by a 1% decrease due to the impact of foreign currency translation. The underlying revenue 
growth reflects an increase in Investments of 9%, Health of 3% and Retirement of 2%, partly offset by a 

33

decrease in Talent of 1%. Oliver Wyman’s revenue increased 17% in 2014 compared to 2013, or 15% on 
an underlying basis, as all industry sectors contributed to this growth. On a geographic basis, the revenue 
growth was attributable to both North America and Europe.

The Consulting segment completed six acquisitions during 2014.

During 2014, Mercer acquired a 34% stake in South Africa-based Alexander Forbes Group Holding 
Limited ("Alexander Forbes"). The Company’s investment in Alexander Forbes is accounted for using the 
equity method of accounting and is included in other assets in the consolidated balance sheets.

Expense

Consulting expenses in 2015 decreased 1%, reflecting increases of 4% in underlying expenses and 1% 
related to acquisitions, partly offset by a 6% decrease from the impact of foreign currency translation. The 
increase in underlying expenses reflects the impact of higher base salaries and incentive compensation 
costs and higher retirement benefit costs, partly offset by the impact of the net benefit from the 
termination of the RRA plan.

Consulting expenses in 2014 increased 4% on both a reported and underlying basis compared to 2013. 
This increase reflects the impact of higher incentive compensation costs, partly offset by lower defined 
benefit pension costs.

Corporate and Other

Corporate expenses in 2015 were $195 million compared to $204 million in 2014. The lower expenses in 
2015 were primarily due to the cost of non-recurring corporate initiatives which occurred in 2014, 
discussed in more detail below.

Corporate expenses in 2014 were $204 million compared to $190 million in 2013. The increase is 
primarily due to corporate initiatives, which include strengthening cyber security protections, expenses 
related to strategic investments and corporate transformation efforts, primarily within the HR and Finance 
functions. 

Discontinued Operations

As part of the disposal transactions for Putnam and Kroll, the Company provided certain indemnities, 
primarily related to pre-transaction tax uncertainties and legal contingencies. In accordance with 
applicable accounting guidance, liabilities were established related to these indemnities at the time of the 
sales and reflected as a reduction of the gain on disposal. Discontinued operations includes charges or 
credits resulting from the settlement or resolution of the indemnified matters, as well as adjustments to the 
liabilities related to such matters.

On December 31, 2014, an agreement was reached between Putnam and the Massachusetts 
Department of Revenue ("DOR") regarding a tax dispute, which was covered under the indemnity 
agreement discussed above. The December 2014 agreement was subject to certain approvals, which 
included the State Attorney General and the Commissioner of the DOR. In January 2015, all necessary 
approvals were received, the agreement was executed and the tax was paid. Concurrently, Putnam and 
the Company executed a settlement agreement to resolve all remaining matters under the indemnity 
agreement. The Company recorded a gain, net of federal tax, of approximately $28 million in 2014 related 
to the settlement with Putnam.

Discontinued operations in 2013 includes estimated costs covered under the indemnity related to the Kroll 
sale as well as tax indemnities related to the Putnam sale.

Interest income earned on corporate funds amounted to $13 million in 2015 compared with $21 million in 
2014, primarily due to a lower level of invested funds in 2015. Interest expense was $163 million in 2015 
compared with $165 million in 2014, due to lower average interest rates in 2015 compared with the prior 
year, partly offset by higher average debt outstanding during 2015.

Interest income earned on corporate funds amounted to $21 million in 2014 compared with $18 million in 
2013. The increase in interest income is due to a higher level of invested funds, partly offset by lower 
effective interest rates. Interest expense was $165 million in 2014 compared with $167 million in 2013.

Cost of Extinguishment of Debt

In October 2014, the Company redeemed $230 million of its 2015 notes and $400 million of its 2019 
notes. The Company acquired the notes at market value plus a make-whole premium based on the terms 
of the original indenture, which exceeded the carrying value of the notes and resulted in a cost of $137 
million in the fourth quarter of 2014.

In October 2013, the Company redeemed $250 million of its 2015 notes. The Company acquired the
notes at market value plus a make-whole premium based on the terms of the original indenture, which
exceeded the carrying value of the notes and resulted in a cost of approximately $24 million in the fourth
quarter of 2013.

Investment Income

The caption "Investment income (loss)" in the consolidated statements of income comprises realized and 
unrealized gains and losses from investments recognized in current earnings. It includes, when 
applicable, other-than-temporary declines in the value of debt and available-for-sale securities and equity 
method gains or losses on its investment in private equity funds. The Company's investments may 
include direct investments in insurance or consulting companies and investments in private equity funds. 
The Company recorded net investment income of $38 million and $37 million in 2015 and 2014, 
respectively, primarily related to the general partner carried interest from Trident III. Stonepoint Capital, 
the investment manager of Trident III, harvested the remaining two investments of Trident III during the 
third quarter of 2015, which resulted in the Company recognizing its remaining deferred performance 
fees.

Income Taxes

The Company's consolidated effective tax rate was 29.1%, 28.5% and 30.1% in 2015, 2014 and 2013, 
respectively. The tax rate in each year reflects foreign operations which are taxed at rates lower than the 
U.S. statutory tax rate. The lower effective tax rate attributed to the Company's foreign operations 
primarily reflects lower corporate tax rates that prevail outside of the U.S., net of the U.S. tax impact from 
repatriating foreign earnings. In 2015, pre-tax income in the U.K., Canada, Australia, Germany, Bermuda 
and Ireland accounted for approximately 60% of the Company's total non-U.S. pre-tax income, with 
effective rates in those countries of 22% (excluding the non-cash deferred tax impact of U.K. tax 

35

legislation enacted in 2015), 27%, 30%, 31%, 1% and 12%, respectively. Under current U.S. tax law, the 
Company anticipates its non-U.S. operations will continue to incur taxes at rates below the U.S. federal 
tax rate of 35%. The Company's U.S. revenue over the past three years has been approximately 46% of 
total revenue, while over that period the pre-tax income from U.S. locations varied from 15% to 30% of 
total pre-tax income.

As a U.S.-domiciled parent holding company, Marsh & McLennan Companies, Inc. is the issuer of 
essentially all of the Company's external indebtedness, and incurs the related interest expense in the U.S. 
Further, most senior executive and oversight functions are conducted in the U.S. and the associated 
costs are incurred primarily in the United States.

The effective tax rate may vary significantly from period to period for the foreseeable future. It is sensitive 
to the geographic mix and repatriation of the Company's earnings, which may result in higher or lower tax 
rates. A proportional increase in U.S. pre-tax income will tend to increase the effective tax rate because 
U.S. federal and state corporate tax rates exceed tax rates applicable outside the U.S. Losses in certain 
jurisdictions cannot be offset by earnings from other operations, and may require valuation allowances 
that affect the rate, depending on estimates of the realizability of associated deferred tax assets. The 
effective tax rate is also sensitive to changes in unrecognized tax benefits, including the impact of settled 
tax audits and expired statutes of limitation.

The realization of deferred tax assets depends on generating future taxable income during the periods in 
which the tax benefits are deductible or creditable. Tax liabilities are determined and assessed 
jurisdictionally by legal entity or filing group. Certain taxing jurisdictions allow or require combined or 
consolidated tax filings. The Company assessed the realizability of its deferred tax assets and considered 
all available evidence, including the existence of a recent history of losses, placing particular weight on 
evidence that could be objectively verified. A valuation allowance was recorded to reduce deferred tax 
assets to the amount that the Company believes is more likely than not to be realized.

Changes in tax laws or tax rulings in any of the jurisdictions in which we operate could have a significant 
adverse impact on our effective tax rate.

Liquidity and Capital Resources

The Company is organized as a holding company, a legal entity separate and distinct from its operating 
subsidiaries. As a holding company without significant operations of its own, the Company is dependent 
upon dividends and other payments from its operating subsidiaries to meet its obligations for paying 
principal and interest on outstanding debt obligations, for paying dividends to stockholders, for share 
repurchases and for corporate expenses. We also provide financial support to our operating subsidiaries 
for acquisitions, investments and certain parts of their business that require liquidity, such as the capital 
markets raising business of Guy Carpenter. Other sources of liquidity include borrowing facilities 
discussed below in financing cash flows.

The Company derives a significant portion of its revenue and operating profit from operating subsidiaries 
located outside of the United States. Funds from the Company’s operating subsidiaries located outside of 
the United States are regularly repatriated to the United States out of annual earnings. At December 31, 
2015, the Company had approximately $800 million of cash and cash equivalents in its foreign 
operations, substantially all of which is considered to be permanently invested in those operations to fund 
foreign investments and working capital needs. At the current time, the Company does not intend to 
repatriate any of this cash. The non-U.S. cash and cash equivalents considered permanently reinvested 
includes $191 million of operating funds required to be maintained for regulatory requirements or as 
collateral under certain captive insurance arrangements. The Company expects to continue its practice of 
repatriating foreign funds out of current annual earnings. While management does not foresee a need to 
repatriate the funds which are currently deemed permanently invested, if facts or circumstances change, 
management could elect to repatriate them, if necessary, which could result in higher effective tax rates in 
the future. During 2015, the Company recorded foreign currency translation adjustments which reduced 
net equity by $643 million. Continued strengthening of the U.S. dollar against foreign currencies would 
further reduce the translated U.S. dollar value of the Company’s net investments in its non-U.S. 
subsidiaries, as well as the translated U.S. dollar value of cash repatriations from those subsidiaries.

36

Cash on our consolidated balance sheets includes funds available for general corporate purposes. Funds 
held on behalf of clients in a fiduciary capacity are segregated and shown separately in the consolidated 
balance sheets as an offset to fiduciary liabilities. Fiduciary funds cannot be used for general corporate 
purposes, and should not be considered as a source of liquidity for the Company.

Operating Cash Flows

The Company generated $1.9 billion of cash from operations in 2015, compared with $2.1 billion in 2014.  
These amounts reflect the net income reported by the Company during those periods, excluding gains or 
losses from investments, cost of extinguishment of debt and the disposition of businesses, adjusted for 
non-cash charges such as depreciation and amortization and changes in working capital which relate, 
primarily, to the timing of payments for accrued liabilities or receipts of assets.

Pension-Related Items

During 2015, the Company contributed $29 million to its U.S. pension plans and $166 million to non-U.S. 
pension plans. In 2014, the Company contributed $25 million to U.S. plans and $156 million to non-U.S. 
plans.

In the U.S., contributions to the tax-qualified defined benefit plans are based on ERISA guidelines and the 
Company generally expects to maintain a funded status of 80% or more of the liability determined under 
the ERISA guidelines. The pension stabilization provisions included in the "Moving Ahead for Progress in 
the 21st Century Act", enacted on July 6, 2012, changed the methodology for determining the discount 
rate used for calculating plan liabilities under ERISA, which determines, in part, the funding requirements.    
After considering the impact of the pension funding stabilization provisions discussed above, there was 
no ERISA funding requirement for the U.S. qualified plan in 2015. The Company made a $0.2 million 
contribution to its tax-qualified U.S. pension plan in the first quarter of 2014. There currently is no ERISA 
funding requirement for the U.S. qualified plan for 2016. The Company expects to fund approximately $26 
million to its non-qualified U.S. pension plans in 2016.

The Company continues to manage the cost and assess the competitiveness of its benefits programs, 
and also to manage the risks related to its defined benefit pension plan liabilities. Effective September 1, 
2015, the Company divided its U.S. qualified defined benefit plan. The existing plan was amended to 
cover only the retirees currently receiving benefits and terminated vested participants as of August 1, 
2015. The Company's active participants as of that date were transferred into a newly established, legally 
separate qualified defined benefit plan. The benefits provided to the plans’ participants were unchanged. 
As a result of the plan amendment and establishment of the new plan, the Company re-measured the 
assets and liabilities of the two plans, as required under U.S. GAAP, based on assumptions and market 
conditions at the amendment date. Net periodic pension expense in 2015 includes the weighted average 
costs of the December 31, 2014 measurement and the September 1, 2015 re-measurement.

Effective August 1, 2015, the Company amended its Ireland defined benefit pension plans to close those 
plans to future benefit accruals and replaced those plans with a defined contribution arrangement. The 
Company re-measured the assets and liabilities of the plans, based on assumptions and market 
conditions on the amendment date.

The Company has a large number of non-U.S. defined benefit pension plans, the largest of which are in 
the U.K., which comprise approximately 83% of non-U.S. plan assets. Contribution rates for non-U.S. 
plans are generally based on local funding practices and statutory requirements, which may differ 
significantly from measurements under U.S. GAAP. In the U.K., contributions to defined benefit pension 
plans are determined through a negotiation process between the Company and the plans' trustee that 
typically occurs every three years in conjunction with the actuarial valuation of the plans. This process is 
governed by U.K. pension regulations. The assumptions that result from the funding negotiations are 
different from those used for U.S. GAAP and currently result in a lower funded status than under U.S. 
GAAP. In March 2014, the Company and the Trustee of the U.K. Defined Benefits Plans agreed to a 
funding deficit recovery plan for the U.K. defined benefit pension plans. The current agreement with the 
Trustee sets out the annual deficit contributions which would be due based on the deficit at December 31, 
2012. The funding level is subject to re-assessment, in most cases on November 1st of each year. If the 
funding level on November 1st is sufficient, no deficit funding contributions will be required in the following 
year, and the contribution amount will be deferred. As part of a long-term strategy, which depends on 

37

having greater influence over asset allocation and overall investment decisions, the Company has agreed 
to support annual deficit contributions by the U.K. operating companies under certain circumstances, up 
to GBP 450 million over a seven-year period ("contingent guarantee agreement").

The Company contributed $51 million to the U.K. plans in 2015. The U.K. employers also contribute an 
expense allowance each year of approximately $9 million. Based on the funding test carried out at 
November 1, 2015, the Company contributions to the U.K. plans in 2016 are expected to be 
approximately $100 million, including the expense allowance.

In the aggregate, the Company expects to contribute approximately $191 million to its non-U.S. defined 
benefit plans in 2016, comprising approximately $91 million to plans outside of the U.K. and $100 million 
to the U.K. plans.

Funding amounts may be influenced by future asset performance, the level of discount rates and other 
variables impacting the funded status of the plan.

After completion of a consultation period with affected colleagues, in January 2014, the Company 
amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective 
August 1, 2014 and replaced those plans, along with its existing defined contribution plans, with a new, 
comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. 
defined benefit plans, and as required under GAAP, the Company re-measured the defined benefit plans’ 
assets and liabilities at the amendment date, based on assumptions and market conditions at that date. 
The Company recognized a curtailment gain of $65 million in the first quarter of 2014, primarily resulting 
from the recognition of the remaining unamortized prior service credit related to a plan amendment made 
in December 2012. This gain was mostly offset by the cost of a transition benefit to certain employees 
most impacted by the amendment.

The year-over-year change in the funded status of the Company's pension plans is impacted by the 
difference between actual and assumed results, particularly with regard to return on assets, and changes 
in the discount rate, as well as the amount of Company contributions, if any. Unrecognized actuarial 
losses were approximately $1.8 billion and $2.9 billion at December 31, 2015 for the U.S. plans and non-
U.S. plans, respectively, compared with $1.7 billion and $3.2 billion at December 31, 2014. The increase 
in the U.S. was due to the increase in the discount rate, partially offset by negative returns on plan assets. 
The decrease in the non-U.S. plans was primarily due to the impact of increases in the discount rates and 
actual returns on plan assets in 2015 that were lower than the estimated long-term rate of return on plan 
assets. In the past several years, the amount of actuarial losses has been significantly impacted, both 
positively and negatively, by actual asset performance and changes in discount rates. The discount rate 
used to measure plan liabilities increased in both the U.S. and the U.K. (the Company's largest plans) in 
2015 after decreasing in 2014. The discount rate increased in 2013 following decreases in each of the 
four years from 2009 to 2012. An increase in the discount rate decreases the measured plan benefit 
obligation, resulting in actuarial gains, while a decrease in the discount rate increases the measured plan 
obligation, resulting in actuarial losses. During 2015, the Company's defined benefit pension plan assets 
had a loss of 3.9% in the U.S. and gain of 1.2% in the U.K. During 2014, the Company's defined benefit 
pension plan assets had actual returns of 9.8% and 19.4% in the U.S. and U.K., respectively, and in 2013, 
actual returns of 12.6%, and 8.6% in the U.S. and U.K., respectively.

Overall, based on the measurement at December 31, 2015, expenses related to the Company’s defined 
benefit pension plans are expected to decrease in 2016 by approximately $165 million from the 2015 
expenses of $82 million. This is driven by expense decreases of approximately $80 million in U.S. plans 
and $85 million in non-U.S. plans. The expense decrease in the U.S. plans results primarily from an 
increase in the discount rates used to measure plan liabilities and costs and the impact of an increase in 
the length of the period over which actuarial gains and losses are amortized, moving to average life 
expectancy for a U.S. plan that has substantially all inactive members. The decrease in the Company’s 
non-U.S. defined benefit plans is due to generally higher discount rates used to measure plan liabilities 
and costs, the impact of the amortization period for actuarial gains and losses moving to average life 
expectancy for plans in Ireland that were frozen and have substantially all inactive members, and a 
change in how the Company estimates the service and interest cost components of net periodic benefit 
costs (described in more detail below), partly offset by lower estimated returns to be earned on plan 
assets.

38

Historically, service and interest costs were estimated using a single weighted average discount rate 
derived from the yield curves used to measure the benefit obligations at the beginning of the period. For 
2016, the Company has changed the approach used to estimate the service and interest cost 
components of net periodic benefit cost for its significant non-U.S. plans. This change in approach was 
made to improve the correlation between the projected benefit cash flows and the corresponding yield 
curve spot rates and to provide a more precise measurement of service and interest costs. The change 
does not impact the measurement of the plans’ total projected benefit obligation. The Company has 
accounted for this change as a change in estimate, that will be applied prospectively beginning in 2016. 
As a result of this change, service and interest cost in 2016 are expected to be approximately $45 million 
lower than if the prior approach were used in 2016. This amount is included in the $85 million decrease 
for non-U.S. plans described above.

The Company’s accounting policies for its defined benefit pension plans, including the selection of and 
sensitivity to assumptions, are discussed below under Management’s Discussion of Critical Accounting 
Policies. For additional information regarding the Company’s retirement plans, see Note 8 to the 
consolidated financial statements.

In March 2015, the Company amended its U.S. Post-65 retiree medical reimbursement plan (the "RRA 
plan"), resulting in its termination, with benefits to certain participants to be paid through December 31, 
2016. As a result of the termination of the RRA plan, the Company recognized a net credit of 
approximately $125 million in the first quarter of 2015.

Financing Cash Flows

Net cash used for financing activities was $906 million in 2015 compared with $968 million used in 2014.

Debt

The Company increased outstanding debt by approximately $1.0 billion in 2015 and $426 million in 2014.

In September 2015, the Company issued $600 million of 3.75% 10.5-year senior notes. The Company  
used the net proceeds for general corporate purposes.

In March 2015, the Company issued $500 million of 2.35% five-year senior notes. The Company used the 
net proceeds for general corporate purposes.

In September 2014, the Company issued $300 million of 2.35% five-year senior notes and $500 million of 
3.50% 10.5-year senior notes. In October 2014, a significant portion of the net proceeds of this offering 
was used to redeem $630 million of debt, including $230 million of 5.75% senior notes due in September 
2015 and $400 million of 9.25% senior notes due in 2019. Total cash outflow related to this transaction 
was approximately $765 million, including a $137 million cost for early redemption, which was reflected as 
a charge in the consolidated statements of income in the fourth quarter of 2014.

During the second quarter of 2014, the Company issued $600 million of 3.5% ten-year senior notes. The 
net proceeds of this offering were used for general corporate purposes, including the repayment of $320 
million of 5.375% senior notes that matured in July 2014.

In September 2013, the Company issued $250 million of 2.55% five-year senior notes and $250 million of 
4.05% ten-year senior notes. The net proceeds of this offering were used for general corporate purposes, 
which included a partial redemption of $250 million of the outstanding principal amount of the existing 
5.75% senior notes due 2015. The redemption settled in October 2013 with a total cash outflow of 
approximately $275 million, including a $24 million cost for early redemption.

Acquisitions

During 2015, the Company paid $47 million of contingent payments related to acquisitions made in prior 
years. These payments are split between financing and operating cash flows in the consolidated 
statements of cash flows. The portion of these payments that is reflected as a financing activity is $13 
million, which represents payments related to the contingent consideration liability that was recorded on 
the date of acquisition. Payments related to increases in the contingent consideration liability subsequent 
to the date of acquisition, which were $34 million in 2015, are reflected as operating cash flows. 
Remaining estimated future contingent consideration payments of $309 million for acquisitions completed 

39

in 2015 and in prior years are included in accounts payable and accrued liabilities or other liabilities in the 
consolidated balance sheet at December 31, 2015. The Company paid deferred purchase consideration 
related to prior years' acquisitions of $36 million, $25 million and $15 million for the years ended 
December 31, 2015, 2014 and 2013, respectively. Remaining deferred cash payments of approximately 
$143 million are included in accounts payable and accrued liabilities or other liabilities in the consolidated 
balance sheet at December 31, 2015.

In 2014, the Company paid $42 million of contingent payments related to acquisitions made in prior 
periods, of which $30 million was reported as financing cash flows and $12 million as operating cash 
flows. In 2013, the Company made $17 million of contingent payments related to acquisitions made in 
prior periods.

Credit Facilities

On November 24, 2015, the Company and certain of its subsidiaries amended its $1.2 billion facility, 
discussed below, into a new $1.5 billion multi-currency five-year unsecured revolving credit facility. The 
interest rate on this facility is based on LIBOR plus a fixed margin which varies with the Company's credit 
ratings. This facility expires in November 2020 and requires the Company to maintain certain coverage 
and leverage ratios which are tested quarterly. There were no borrowings outstanding under this facility at 
December 31, 2015.

The Company and certain of its subsidiaries previously maintained a $1.2 billion multi-currency five-year 
revolving credit facility. The facility was previously due to expire in March 2019 and was in effect until 
November 2015. There were no borrowings outstanding under this facility at the time it was amended.

The Company has a $150 million uncommitted bank credit line. There were no borrowings under this 
facility at December 31, 2015.

In December 2012, the Company closed on a $50 million, three-year delayed draw term loan facility. The 
interest rate on this facility was based on LIBOR plus an agreed fixed margin which varied with the 
Company's credit ratings. The loan was repaid and the facility was terminated on October 30, 2015.

The Company's senior debt is currently rated A- by Standard & Poor's and Baa1 by Moody's. The 
Company's short-term debt is currently rated A-2 by Standard & Poor's and P-2 by Moody's. The 
Company carries a stable outlook from both firms.

The Company also maintains other credit facilities, guarantees and letters of credit with various banks, 
primarily related to operations located outside the United States, aggregating $229 million at 
December 31, 2015 and $260 million at December 31, 2014. There was $0.4 million outstanding 
borrowings under these facilities at December 31, 2015 and $0.6 million outstanding borrowings under 
these facilities at December 31, 2014.

Share Repurchases

In May 2015, the Board of Directors renewed the Company's share repurchase program, allowing 
management to buy back up to $2 billion of shares going forward. During 2015, the Company 
repurchased 24.8 million shares of its common stock for total consideration of $1.4 billion at an average 
price per share of $56.46. As of December 31, 2015, the Company remained authorized to purchase 
additional shares of its common stock up to a value of approximately $1.2 billion. There is no time limit on 
this authorization. During 2014, the Company repurchased 15.5 million shares of its common stock for 
total consideration of $800 million at an average price per share of $51.44.

Dividends

The Company paid total dividends of $632 million in 2015 ($1.18 per share), $582 million in 2014 ($1.06 
per share) and $533 million in 2013 ($0.96 per share).

Investing Cash Flows

Net cash used for investing activities amounted to $1.3 billion in 2015 compared with $1.2 billion used for 
investing activities in 2014. 

The Company made 21 acquisitions in 2015. Cash used for these acquisitions, net of cash acquired, was 
$952 million. 

On June 23, 2014, Mercer acquired 34% of the common shares of South Africa-based Alexander Forbes 
Group Holdings Limited ("Alexander Forbes"). Mercer purchased its stake in Alexander Forbes in two 
tranches at 7.50 South African Rand per share at an aggregate purchase price of approximately $300 
million. The investment in Alexander Forbes is accounted for using the equity method and is included in 
other assets in the consolidated balance sheets. 

The Company made 21 acquisitions in 2014. Cash used for these acquisitions, net of cash acquired, was 
$554 million.  

The Company received proceeds from distributions on its Investment in Trident II of $100 million in 2013. 
Trident II fully harvested all its portfolio investments and made final distributions to partners during the 
fourth quarter of 2013. 

The Company’s additions to fixed assets and capitalized software, which amounted to $325 million in 
2015 and $368 million in 2014, primarily relate to computer equipment purchases, the refurbishing and 
modernizing of office facilities and software development costs. 

On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) 
constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The 
purchase price for the BNFT shares and certain other rights and other consideration was approximately 
$75 million.

The Company has commitments for potential future investments of approximately $54 million in four 
private equity funds that invest primarily in financial services companies.

The above does not include the liability for unrecognized tax benefits of $74 million as the Company is 
unable to reasonably predict the timing of settlement of these liabilities, other than approximately $3 
million that may become payable during 2016. The above does not include the indemnified liabilities 
discussed in Note 15 as the Company is unable to reasonably predict the timing of settlement of these 
liabilities. The above does not include net pension liabilities of approximately $1.9 billion because the 
timing and amount of ultimate payment of such liability is dependent upon future events, including, but not 
limited to, future returns on plan assets and changes in the discount rate used to measure the liabilities. 
The amounts of estimated future benefits payments to be made from pension plan assets are disclosed in 
Note 8 to the consolidated financial statements. In 2016, the Company expects to contribute 
approximately $26 million and $191 million to its U.S. and non-U.S. pension plans, respectively.

Management’s Discussion of Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the 
United States ("GAAP") requires management to make estimates and judgments that affect reported 
amounts of assets, liabilities, revenue and expenses, and disclosure of contingent assets and liabilities. 
Management considers the policies discussed below to be critical to understanding the Company’s 
financial statements because their application places the most significant demands on management’s 
judgment, and requires management to make estimates about the effect of matters that are inherently 
uncertain. Actual results may differ from those estimates.

Legal and Other Loss Contingencies

The Company and its subsidiaries are subject to numerous claims, lawsuits and proceedings including 
claims for errors and omissions ("E&O"). GAAP requires that a liability be recorded when a loss is both 
probable and reasonably estimable. Significant management judgment is required to apply this guidance. 
The Company utilizes case level reviews by inside and outside counsel, an internal actuarial analysis and 
other analyses to estimate potential losses. The liability is reviewed quarterly and adjusted as 
developments warrant. In many cases, the Company has not recorded a liability, other than for legal fees 
to defend the claim, because we are unable, at the present time, to make a determination that a loss is 
both probable and reasonably estimable. Given the unpredictability of E&O claims and of litigation that 
could flow from them, it is possible that an adverse outcome in a particular matter could have a material 
adverse effect on the Company’s businesses, results of operations, financial condition or cash flow in a 
given quarterly or annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is 
required to determine the amount of recoveries that are probable of collection under the Company’s 
various insurance programs.

Retirement Benefits

The Company maintains qualified and non-qualified defined benefit pension and defined contribution 
plans for its eligible U.S. employees and a variety of defined benefit and defined contribution plans for its 
eligible non-U.S. employees. The Company’s policy for funding its tax-qualified defined benefit retirement 
plans is to contribute amounts at least sufficient to meet the funding requirements set forth in U.S. and 
applicable foreign laws.

The Company recognizes the funded status of its over-funded defined benefit pension and retiree medical 
plans as a net benefit plan asset and its unfunded and underfunded plans as a net benefit plan liability. 
The gains or losses and prior service costs or credits that have not been recognized as components of 
net periodic costs are recorded as a component of Accumulated Other Comprehensive Income ("AOCI"), 
net of tax, in the Company’s consolidated balance sheets. The gains and losses that exceed specified 
corridors are amortized prospectively out of AOCI over a period that approximates the average remaining 
service period of active employees, or for plans in which substantially all the participants are inactive, 
over the remaining life expectancy of the inactive employees.

The determination of net periodic pension cost is based on a number of assumptions, including an 
expected long-term rate of return on plan assets, the discount rate, mortality and assumed rate of salary 
increase. Significant assumptions used in the calculation of net periodic pension costs and pension 
liabilities are disclosed in Note 8 to the consolidated financial statements. The Company believes the 
assumptions for each plan are reasonable and appropriate and will continue to evaluate assumptions at 
least annually and adjust them as appropriate.

42

Future pension expense or credits will depend on plan provisions, future investment performance, future 
assumptions and various other factors related to the populations participating in the pension plans. 
Holding all other assumptions constant, a half-percentage point change in the rate of return on plan 
assets and discount rate assumptions would affect net periodic pension cost for the U.S. and U.K. plans, 
which together comprise approximately 86% of total pension plan liabilities, as follows:

(In millions of dollars)
Assumed Rate of Return on Plan Assets

$

Changing the discount rate and leaving the other assumptions constant may not be representative of the 
impact on expense, because the long-term rates of inflation and salary increases are often correlated with 
the discount rate. Changes in these assumptions will not necessarily have a linear impact on the net 
periodic pension cost.

The Company contributes to certain health care and life insurance benefits provided to its retired 
employees. The cost of these post-retirement benefits for employees in the U.S. is accrued during the 
period up to the date employees are eligible to retire, but is funded by the Company as incurred. The key 
assumptions and sensitivity to changes in the assumed health care cost trend rate are discussed in Note 
8 to the consolidated financial statements.

Income Taxes

The Company's tax rate reflects its income, statutory tax rates and tax planning in the various jurisdictions 
in which it operates. Significant judgment is required in determining the annual effective tax rate and in 
evaluating uncertain tax positions. The Company reports a liability for unrecognized tax benefits resulting 
from uncertain tax positions taken or expected to be taken in a tax return. The evaluation of a tax position 
is a two-step process. The first step involves recognition. The Company determines whether it is more 
likely than not that a tax position will be sustained upon tax examination, including resolution of any 
related appeals or litigation, based on only the technical merits of the position. The technical merits of a 
tax position derive from both statutory and judicial authority (legislation and statutes, legislative intent, 
regulations, rulings, and case law) and their applicability to the facts and circumstances of the tax 
position. If a tax position does not meet the more likely than not recognition threshold, the benefit of that 
position is not recognized in the financial statements. The second step is measurement. A tax position 
that meets the more likely than not recognition threshold is measured to determine the amount of benefit 
to recognize in the financial statements. The tax position is measured as the largest amount of benefit 
that is greater than 50 percent likely of being realized upon ultimate resolution with a taxing authority.

Uncertain tax positions are evaluated based upon the facts and circumstances that exist at each reporting 
period and involve significant management judgment. Subsequent changes in judgment based upon new 
information may lead to changes in recognition, derecognition, and measurement. Adjustments may 
result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of 
limitations barring an assessment for an issue.

Tax law requires items be included in the Company's tax returns at different times than the items are 
reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated 
statements of income is different than that reported in the tax returns. Some of these differences are 
permanent, such as expenses that are not deductible in the returns, and some differences are temporary 
and reverse over time, such as depreciation expense. Temporary differences create deferred tax assets 
and liabilities. Deferred tax liabilities generally represent tax expense recognized in the financial 
statements for which payment has been deferred, or expense for which a deduction has been taken 
already in the tax return but the expense has not yet been recognized in the financial statements.   
Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns 
in future years for which a benefit has already been recorded in the financial statements. In assessing the 
need for and amount of a valuation allowance for deferred tax assets, the Company considers whether it 
is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts 

43

the valuation allowance accordingly. The Company evaluates all significant available positive and 
negative evidence, including the existence of losses in recent years and its forecast of future taxable 
income by jurisdiction, in assessing the need for a valuation allowance. The Company also considers tax 
planning strategies that would result in realization of deferred tax assets, and the presence of taxable 
income in prior period tax filings in jurisdictions that allow for the carryback of tax attributes pursuant to 
the applicable tax law. The underlying assumptions the Company uses in forecasting future taxable 
income require significant judgment and take into account the Company's recent performance. The 
ultimate realization of deferred tax assets is dependent on the generation of future taxable income during 
the periods in which temporary differences or carry-forwards are deductible or creditable. Valuation 
allowances are established for deferred tax assets when it is estimated that it is more likely than not that 
future taxable income will be insufficient to fully use a deduction or credit in that jurisdiction.

Fair Value Determinations

Goodwill Impairment Testing—The Company is required to assess goodwill and any indefinite-lived 
intangible assets for impairment annually, or more frequently if circumstances indicate impairment may 
have occurred. The Company performs the annual impairment test for each of its reporting units during 
the third quarter of each year. In accordance with applicable accounting guidance, the Company 
assesses qualitative factors to determine whether it is necessary to perform the two-step goodwill 
impairment test. The Company considered numerous factors, which included that the fair value of each 
reporting unit exceeded its carrying value by a substantial margin in its most recent estimate of reporting 
unit fair values, whether significant acquisitions or dispositions occurred which might alter the fair value of 
its reporting units, macroeconomic conditions and their potential impact on reporting unit fair values, 
actual performance compared with budget and prior projections used in its estimation of reporting unit fair 
values, industry and market conditions, and the year-over-year change in the Company’s share price.

The Company completed its qualitative assessment in the third quarter of 2015 and concluded that a two-
step goodwill impairment test was not required in 2015 and that goodwill was not impaired.

Share-based Payment

The guidance for accounting for share-based payments requires, among other things, that the estimated 
fair value of stock options be charged to earnings. Significant management judgment is required to 
determine the appropriate assumptions for inputs such as volatility and expected term necessary to 
estimate option values. In addition, management judgment is required to analyze the terms of the plans 
and awards granted thereunder to determine if awards will be treated as equity awards or liability awards, 
as defined by the accounting guidance.

As of December 31, 2015, there was $11.8 million of unrecognized compensation cost related to stock 
option awards. The weighted-average period over which the costs are expected to be recognized is 1.16 
years. Also as of December 31, 2015, there was $94.5 million of unrecognized compensation cost related 
to the Company’s restricted stock, restricted stock unit and performance stock unit awards. The weighted-
average period over which that cost is expected to be recognized is approximately 1.1 years.

See Note 9 to the consolidated financial statements for additional information regarding accounting for 
share-based payments.

New Accounting Pronouncements

Note 1 to the consolidated financial statements contains a summary of the Company’s significant 
accounting policies, including a discussion of recently issued accounting pronouncements and their 
impact or potential future impact on the Company’s financial results, if determinable, under the sub-
heading "New Accounting Pronouncements".

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

Market Risk and Credit Risk

Certain of the Company’s revenues, expenses, assets and liabilities are exposed to the impact of interest 
rate changes and fluctuations in foreign currency exchange rates and equity markets.

Interest Rate Risk and Credit Risk

Interest income generated from the Company’s cash investments as well as invested fiduciary funds will 
vary with the general level of interest rates.

The Company had the following investments subject to variable interest rates: 

(In millions of dollars)
Cash and cash equivalents invested in money market funds, certificates of
deposit and time deposits

Fiduciary cash and investments

December 31,
2015

$

$

1,374

4,146

Based on the above balances, if short-term interest rates increased or decreased by 10%, or 6 basis 
points, over the course of the year, annual interest income, including interest earned on fiduciary funds, 
would increase or decrease by approximately $2 million.

In addition to interest rate risk, our cash investments and fiduciary fund investments are subject to 
potential loss of value due to counter-party credit risk. To minimize this risk, the Company and its 
subsidiaries invest pursuant to a Board approved investment policy. The policy mandates the preservation 
of principal and liquidity and requires broad diversification with counter-party limits assigned based 
primarily on credit rating and type of investment. The Company carefully monitors its cash and fiduciary 
fund investments and will further restrict the portfolio as appropriate to market conditions. The majority of 
cash and fiduciary fund investments are invested in short-term bank deposits and liquid money market 
funds.

Foreign Currency Risk

The translated values of revenue and expense from the Company’s international operations are subject to 
fluctuations due to changes in currency exchange rates. The non-U.S. based revenue that is exposed to 
foreign exchange fluctuations is approximately 51% of total revenue. We periodically use forward 
contracts and options to limit foreign currency exchange rate exposure on net income and cash flows for 
specific, clearly defined transactions arising in the ordinary course of business. Although the Company 
has significant revenue generated in foreign locations which is subject to foreign exchange rate 
fluctuations, in most cases both the foreign currency revenue and expenses are in the functional currency 
of the foreign location. As such, under normal circumstances, the U.S. dollar translation of both the 
revenues and expenses, as well as the potentially offsetting movements of various currencies against the 
U.S. dollar, generally tends to mitigate the impact on net operating income of foreign currency risk. If 
foreign exchange rates of major currencies (Euro, Sterling, Australian dollar and Canadian dollar) moved 
10% in the same direction against the U.S. dollar compared with the foreign exchange rates in 2015, the 
Company estimates net operating income would increase or decrease by approximately $50 million. The 
Company has exposure to approximately 80 foreign currencies overall. Starting at the end of 2014 and 
continuing through 2015, the U.S. dollar strengthened significantly against most currencies, which had a 
significant impact on net operating income in 2015. If exchange rates at January 31, 2016 hold constant 
throughout 2016, the Company estimates the year-over-year impact from conversion of foreign currency 
earnings will reduce full year income by approximately $50 million. In Continental Europe, the largest 
amount of revenue from renewals for the Risk & Insurance segment occurs in the first quarter. 
Consequently, a significant portion of the year-over-year foreign exchange impact is expected to occur in 
the first quarter.

45

Equity Price Risk

The Company holds investments in both public and private companies as well as private equity funds that 
invest primarily in financial services companies. Investments of approximately $20 million are classified as 
available for sale, approximately $76 million are accounted for using the cost method, which includes the 
Company's investment in Benefitfocus, and $347 million are accounted for using the equity method, 
which includes the Company's investments in Alexander Forbes. The investments are subject to risk of 
changes in market value, which, if determined to be other than temporary, could result in realized 
impairment losses. The Company periodically reviews the carrying value of such investments to 
determine if any valuation adjustments are appropriate under the applicable accounting pronouncements.

At December 31, 2015, the carrying value of the Company's investment in Alexander Forbes, purchased 
at 7.50 South African Rand per share, was approximately $230 million. The market value of the 
Company's shares, based on the closing share price of 5.78 Rand per share, was approximately $166 
million. During 2015, the share price of Alexander Forbes ranged from 10.38 Rand to 5.32 Rand. The 
trading price first dropped below MMC's purchase price at the end of November 2015. The Company 
considered several factors related to its investment in Alexander Forbes, including its financial position, 
the near- and long-term prospects of Alexander Forbes and the broader South African economy and 
capital markets, the length of time and extent to which the market value was below cost, and the 
Company’s intent and ability to retain the investment for a sufficient period of time to allow for anticipated 
recovery in market value. As a result, the Company determined the investment was not impaired.

A number of lawsuits and regulatory proceedings are pending. See Note 15 to the consolidated financial

MARSH & McLENNAN COMPANIES, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.    Summary of Significant Accounting Policies

Nature of Operations:  Marsh & McLennan Companies, Inc. (the "Company”), a global professional 
services firm, is organized based on the different services that it offers. Under this organizational 
structure, the Company’s two business segments are Risk and Insurance Services and Consulting.

The Risk and Insurance Services segment provides risk management activities and insurance broking, 
reinsurance broking and insurance program management services for businesses, public entities, 
insurance companies, associations, professional services organizations, and private clients. The 
Company conducts business in this segment through Marsh and Guy Carpenter.

The Company conducts business in its Consulting segment through two main business groups. Mercer 
provides consulting expertise, advice, services and solutions in the areas of health, retirement, talent and 
investments. Oliver Wyman Group provides specialized management and economic and brand consulting 
services.

Acquisitions impacting the Risk and Insurance Services and Consulting segments are discussed in Note 
4 below.

Principles of Consolidation:  The accompanying consolidated financial statements include all wholly-
owned and majority-owned subsidiaries. All significant inter-company transactions and balances have 
been eliminated.

Fiduciary Assets and Liabilities:  In its capacity as an insurance broker or agent, the Company 
generally collects premiums from insureds and, after deducting its commissions, remits the premiums to 
the respective insurance underwriters. The Company also collects claims or refunds from underwriters on 
behalf of insureds. Unremitted insurance premiums and claims proceeds are held by the Company in a 
fiduciary capacity. Risk and Insurance Services revenue includes interest on fiduciary funds of $21 million, 
$24 million and $27 million in 2015, 2014 and 2013, respectively. The Consulting segment recorded 
fiduciary interest income of $4 million, $6 million and $5 million in 2015, 2014 and 2013, respectively. 
Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance 
sheets as an offset to fiduciary liabilities.

Net uncollected premiums and claims and the related payables were $6.9 billion and $7.3 billion at 
December 31, 2015 and 2014, respectively. The Company is not a principal to the contracts under which 
the right to receive premiums or the right to receive reimbursement of insured losses arises. Net 
uncollected premiums and claims and the related payables are, therefore, not assets and liabilities of the 
Company and are not included in the accompanying consolidated balance sheets.

In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or 
insureds prior to collection. These advances are made from corporate funds and are reflected in the 
accompanying consolidated balance sheets as receivables.

Mercer manages approximately $21 billion of assets in trusts or funds for which Mercer’s management or 
trustee fee is considered a variable interest. Mercer is not the primary beneficiary of these trusts or funds. 
Mercer’s only variable interest in any of these trusts or funds is its unpaid fees, if any. Mercer’s maximum 
exposure to loss of its interests is, therefore, limited to collection of its fees.

Revenue:  Risk and Insurance Services revenue includes insurance commissions, fees for services 
rendered and interest income on certain fiduciary funds. Insurance commissions and fees for risk transfer 
services generally are recorded as of the effective date of the applicable policies or, in certain cases 
(primarily in the Company's reinsurance broking operations), as of the effective date or billing date, 
whichever is later. A reserve for policy cancellation is provided based on historic and current data on 
cancellations. Consideration for fee arrangements covering multiple insurance placements, the provision 
of risk management and/or other services are allocated to all deliverables on the basis of their relative 
selling prices. Fees for non-risk transfer services provided to clients are recognized over the period in 
which the services are provided, using a proportional performance model. Fees resulting from 

52

achievement of certain performance thresholds are recorded when such levels are attained and such fees 
are not subject to forfeiture.

Consulting revenue includes fees paid by clients for advice and services and commissions from insurance 
companies for the placement of individual and group contracts. Fee revenue for engagements where 
remuneration is based on time plus out-of-pocket expenses is recognized based on the amount of time 
consulting professionals expend on the engagement. For fixed fee engagements, revenue is recognized 
using a proportional performance model. Revenue from insurance commissions not subject to a fee 
arrangement is recorded over the effective period of the applicable policies. Revenue for asset based 
fees is recognized on an accrual basis by applying the daily/monthly rate as contractually agreed with the 
client to the applicable net asset value. On a limited number of engagements, performance fees may also 
be earned for achieving certain prescribed performance criteria. Such fees are recognized when the 
performance criteria have been achieved and, when required, agreed to by the client. Reimbursable 
expenses incurred by professional staff in the generation of revenue and sub-advisory fees related to the 
majority of funds in the investment management business are included in revenue and the related 
expenses are included in other operating expenses.

Cash and Cash Equivalents:  Cash and cash equivalents primarily consist of certificates of deposit and 
time deposits, with original maturities of three months or less, and money market funds. The estimated 
fair value of the Company's cash and cash equivalents approximates their carrying value. The Company 
is required to maintain operating funds primarily related to regulatory requirements outside the U.S. or as 
collateral under captive insurance arrangements. At December 31, 2015, the Company maintained $209 
million related to these regulatory requirements.

Fixed Assets:  Fixed assets are stated at cost less accumulated depreciation and amortization. 
Expenditures for improvements are capitalized. Upon sale or retirement, the cost and related 
accumulated depreciation and amortization are removed from the accounts and any gain or loss is 
reflected in income. Expenditures for maintenance and repairs are charged to operations as incurred.

Depreciation of buildings, building improvements, furniture, and equipment is provided on a straight-line 
basis over the estimated useful lives of these assets. Furniture and equipment is depreciated over 
periods ranging from three to ten years. Leasehold improvements are amortized on a straight-line basis 
over the periods covered by the applicable leases or the estimated useful life of the improvement, 
whichever is less. Buildings are depreciated over periods ranging from thirty to forty years. The Company 
periodically reviews long-lived assets for impairment whenever events or changes indicate that the 
carrying value of assets may not be recoverable.

The components of fixed assets are as follows:

Investments:  The Company holds investments in private companies and private equity funds.

Investments in private equity funds are accounted for under the equity method of accounting using a 
consistently applied three-month lag period adjusted for any known significant changes from the lag 
period to the reporting date of the Company. The underlying private equity funds follow investment 
company accounting, where investments within the fund are carried at fair value. The Company records in 
earnings, investment gains/losses for its proportionate share of the change in fair value of the funds.  
Investments using the equity method of accounting are included in other assets in the consolidated 
balance sheets.

53

 
As part of the sale of MMC Capital in 2005, the Company retained the rights to receive certain 
performance fees related to the Trident II and Trident III private equity partnerships. The Company 
recognizes performance fee income when such fees are no longer subject to forfeiture, which may take a 
number of years to resolve. This income is based on the investment performance over the life of each 
investment in the private equity fund, and future declines in the fund performance from current levels may 
result in forfeiture of such revenue. Since Trident II fully harvested all its portfolio investments and made 
final distributions to its partners in 2013, the Company no longer holds any rights to Trident II performance 
fees. In 2015, the Company recorded investment income of $38 million compared to $37 million in 2014 
and $69 million in 2013. The Company recorded investment income related to its general partner carried 
interest from Trident III no longer subject to clawback of $29 million, $31 million and $41 million in 2015,  
2014 and 2013, respectively. In 2013, the Company recorded $15 million of general partner carried 
interest from Trident II. Stonepoint Capital, the investment manager of Trident III, harvested its remaining 
two investments in Trident III in the third quarter of 2015, which resulted in the Company recognizing its 
remaining deferred performance fees.

Goodwill and Other Intangible Assets:  Goodwill represents acquisition costs in excess of the fair value 
of net assets acquired. Goodwill is reviewed at least annually for impairment. The Company performs an 
annual impairment test for each of its reporting units during the third quarter of each year. When a step 1 
test is performed, fair values of the reporting units are estimated using either a market approach or a 
discounted cash flow model. Carrying values for the reporting units are based on balances at the prior 
quarter end and include directly identified assets and liabilities as well as an allocation of those assets 
and liabilities not recorded at the reporting unit level. As discussed in Note 6, the Company may elect to 
assess qualitative factors to determine if a step 1 test is necessary. Other intangible assets, which 
primarily consist of customer lists that are not deemed to have an indefinite life, are amortized over their 
estimated lives, typically ranging from 10 to 15 years, and reviewed for impairment upon the occurrence 
of certain triggering events in accordance with applicable accounting literature. The Company had no 
indefinite lived identified intangible assets at December 31, 2015 and 2014.

Capitalized Software Costs:  The Company capitalizes certain costs to develop, purchase or modify 
software for the internal use of the Company. These costs are amortized on a straight-line basis over 
periods ranging from 3 to 10 years. Costs incurred during the preliminary project stage and post 
implementation stage, are expensed as incurred. Costs incurred during the application development 
stage are capitalized. Costs related to updates and enhancements are only capitalized if they will result in 
additional functionality. Capitalized computer software costs of $498 million and $501 million, net of 
accumulated amortization of $958 million and $837 million at December 31, 2015 and 2014, respectively, 
are included in other assets in the consolidated balance sheets.

Legal and Other Loss Contingencies:  The Company and its subsidiaries are subject to a significant 
number of claims, lawsuits and proceedings including claims for errors and omissions ("E&O"). The 
preparation of financial statements in conformity with accounting principles generally accepted in the 
United States ("GAAP") requires that a liability be recorded when a loss is both probable and reasonably 
estimable. Significant management judgment is required to apply this guidance. The Company utilizes 
case level reviews by inside and outside counsel, an internal actuarial analysis and other analysis to 
estimate potential losses. The liability is reviewed quarterly and adjusted as developments warrant. In 
many cases, the Company has not recorded a liability, other than for legal fees to defend the claim, 
because we are unable, at the present time, to make a determination that a loss is both probable and 
reasonably estimable. Given the unpredictability of E&O claims and of litigation that could flow from them, 
it is possible that an adverse outcome in a particular matter could have a material adverse effect on the 
Company’s businesses, results of operations, financial condition or cash flow in a given quarterly or 
annual period.

In addition, to the extent that insurance coverage is available, significant management judgment is 
required to determine the amount of recoveries that are probable of collection under the Company’s 
various insurance programs.

The legal and other contingent liabilities described above are not discounted.

54

Income Taxes:  The Company's effective tax rate reflects its income, statutory tax rates and tax planning 
in the various jurisdictions in which it operates. Significant judgment is required in determining the annual 
effective tax rate and in evaluating uncertain tax positions and the ability to realize deferred tax assets.

The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken 
or expected to be taken in a tax return. The evaluation of a tax position is a two-step process. The first 
step involves recognition. The Company determines whether it is more likely than not that a tax position 
will be sustained upon tax examination, including resolution of any related appeals or litigation, based on 
only the technical merits of the position. The technical merits of a tax position derive from both statutory 
and judicial authority (legislation and statutes, legislative intent, regulations, rulings, and case law) and 
their applicability to the facts and circumstances of the tax position. If a tax position does not meet the 
more likely than not recognition threshold, the benefit of that position is not recognized in the financial 
statements. The second step is measurement. A tax position that meets the more likely than not 
recognition threshold is measured to determine the amount of benefit to recognize in the financial 
statements. The tax position is measured as the largest amount of benefit that is greater than 50 percent 
likely to be realized upon ultimate resolution with a taxing authority. Uncertain tax positions are evaluated 
based upon the facts and circumstances that exist at each reporting period. Subsequent changes in 
judgment based upon new information may lead to changes in recognition, de-recognition, and 
measurement. Adjustments may result, for example, upon resolution of an issue with the taxing 
authorities, or expiration of a statute of limitations barring an assessment for an issue. The Company 
recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Tax law requires items to be included in the Company's tax returns at different times than the items are 
reflected in the financial statements. As a result, the annual tax expense reflected in the consolidated 
statements of income is different than that reported in the income tax returns. Some of these differences 
are permanent, such as expenses that are not deductible in the returns, and some differences are 
temporary and reverse over time, such as depreciation expense. Temporary differences create deferred 
tax assets and liabilities. Deferred tax assets generally represent items that can be used as a tax 
deduction or credit in tax returns in future years for which benefit has already been recorded in the 
financial statements. Valuation allowances are established for deferred tax assets when it is estimated 
that future taxable income will be insufficient to use a deduction or credit in that jurisdiction. Deferred tax 
liabilities generally represent tax expense recognized in the financial statements for which payment has 
been deferred, or expense for which a deduction has been taken already in the tax return but the expense 
has not yet been recognized in the financial statements.

Derivative Instruments:  All derivatives, whether designated in hedging relationships or not, are 
recorded on the balance sheet at fair value. If the derivative is designated as a fair value hedge, the 
changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are 
recognized in earnings. The fair value of the derivative is recorded in the consolidated balance sheet in 
other receivables or accounts payable and accrued liabilities. The change in the fair value of a derivative 
is recorded in the consolidated statement of income in other operating expenses. If the derivative is 
designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are 
recorded in other comprehensive income and are recognized in the income statement when the hedged 
item affects earnings. Changes in the fair value attributable to the ineffective portion of cash flow hedges 
are recognized in earnings.

Concentrations of Credit Risk:  Financial instruments which potentially subject the Company to 
concentrations of credit risk consist primarily of cash and cash equivalents, commissions and fees 
receivable and insurance recoverable. The Company maintains a policy providing for the diversification of 
cash and cash equivalent investments and places its investments in a large number of high quality 
financial institutions to limit the amount of credit risk exposure. Concentrations of credit risk with respect 
to receivables are generally limited due to the large number of clients and markets in which the Company 
does business, as well as the dispersion across many geographic areas.

Per Share Data: Basic net income per share attributable to the Company and income from continuing 
operations per share are calculated by dividing the respective after-tax income attributable to common 
shares by the weighted average number of outstanding shares of the Company’s common stock.

55

Diluted net income per share attributable to the Company and income from continuing operations per 
share are calculated by dividing the respective after-tax income attributable to common shares by the 
weighted average number of outstanding shares of the Company’s common stock, which have been 
adjusted for the dilutive effect of potentially issuable common shares. Reconciliations of the applicable 
income components used for diluted EPS - Continuing Operations and basic weighted average common 
shares outstanding to diluted weighted average common shares outstanding are presented below. The 
reconciling items related to the calculation of diluted weighted average common shares outstanding are 
the same for net income attributable to the Company.

There were 14.8 million, 18.0 million and 22.6 million stock options outstanding as of December 31, 2015,

Estimates:  GAAP requires management to make estimates and assumptions that affect the reported 
amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial 
statements, and the reported amounts of revenues and expenses during the reporting period. Actual 
results may vary from those estimates.

New Accounting Pronouncements:  In September 2015, the Financial Accounting Standards Board 
(the "FASB") issued new guidance intended to simplify the accounting for adjustments made to 
provisional amounts recognized in business combinations. The guidance requires the acquirer to 
recognize adjustments to estimated amounts that are identified during the measurement period in the 
reporting period in which the adjustments are determined, and to record, in the same period's financial 
statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if 
any, as a result of the change to the estimated amounts, calculated as if the accounting had been 
completed as of the acquisition date. The guidance also includes additional disclosures required for the 
amounts recorded in current period earnings arising from such adjustments. The guidance is effective for 
fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The 
guidance should be applied prospectively for adjustments to provisional amounts after the effective date, 
with earlier application permitted for financial statements that have not been issued. The adoption of this 
new guidance is not expected to have a material impact on the Company's financial statements.

In May 2015, the FASB issued new guidance which removes the requirement to present certain 
investments for which the practical expedient is used to measure fair value at net asset value within the 
fair value hierarchy table. Instead, an entity would be required to include those investments as a 
reconciling item so that the total fair value amount of investments in the disclosure is consistent with the 
fair value investment balance on the statement of net assets. This guidance is effective for fiscal years 
beginning after December 15, 2015. The adoption of this new guidance will affect footnote disclosure and 
is not expected to have a material impact on the Company's financial statements.

In February 2015, the FASB issued new accounting guidance intended to improve targeted areas of 
consolidation guidance for legal entities such as limited partnerships, limited liability corporations and 
securitization structures. The guidance focuses on the consolidation evaluation for reporting organizations 
that are required to evaluate whether they should consolidate certain legal entities. The guidance is 
effective for periods beginning after December 15, 2015. Early adoption is permitted, including adoption in 

56

an interim period. The adoption of this guidance is not expected to have a material impact on the 
Company's financial statements.

In January 2015, the FASB issued new accounting guidance that eliminated the concept of extraordinary 
items. The guidance is effective for annual periods beginning after December 15, 2015. The guidance 
may be adopted prospectively, or retrospectively to all prior periods presented in the financial statements. 
Early adoption is permitted provided the guidance is applied from the beginning of the fiscal year of 
adoption. Adoption of the guidance is not expected to materially affect the Company's financial condition, 
results of operations or cash flows.

In June 2014, the FASB issued new accounting guidance to clarify the treatment of share-based payment 
awards that require a specific performance target to be achieved in order for employees to be eligible to 
vest in the awards which include terms that may provide that the performance conditions could be 
achieved after an employee completes the requisite service period. The guidance requires that a 
performance target that affects vesting and that could be achieved after the requisite service period be 
treated as a performance condition. As such, a reporting entity should apply the existing guidance as it 
relates to awards with performance conditions that affect vesting. The guidance is effective for annual 
periods beginning after December 15, 2015. Earlier adoption is permitted. Adoption of the guidance is not 
expected to materially affect the Company's financial condition, results of operations or cash flows.

In May 2014, the FASB issued new accounting guidance to clarify the principles for revenue recognition. 
The core principle of the guidance is that an entity should recognize revenue to depict the transfer of 
promised goods or services to customers in an amount that reflects the consideration to which the entity 
expects to be entitled in exchange for those goods or services. To achieve that principle, the entity should 
apply the following steps: identify the contract(s) with the customer, identify the performance obligations in 
the contract(s), determine the transaction price, allocate the transaction price to the performance 
obligations in the contract and recognize revenue when (or as) the entity satisfies a performance 
obligation. The guidance is effective for fiscal years beginning after December 15, 2017, including interim 
periods within that reporting period. Early application is not permitted. Entities are permitted to adopt the 
guidance under one of the following methods: retrospectively to each prior reporting period presented 
(with certain practical expedients allowed) or retrospectively with the cumulative effect of initially applying 
the guidance recognized at the date of initial application. If an entity elects this transition method, it must 
provide disclosures in reporting periods that include the date of initial application of the amount by which 
each financial statement line item is affected in the current reporting period by application of the guidance 
as compared to guidance that was in effect before the change, and an explanation for the reasons for 
significant changes. The Company is currently evaluating the impact of the adoption of the guidance on 
its financial condition and results of operations.

New Accounting Pronouncements Recently Adopted

In November 2015, the FASB issued a new standard related to the balance sheet classification of 
deferred taxes ("deferred tax standard"), which simplifies the presentation of deferred income taxes. The 
deferred tax standard requires companies to classify deferred tax assets and liabilities as noncurrent in 
the consolidated balance sheet. The previous standard required companies to classify deferred tax assets 
and liabilities as current and noncurrent. The deferred tax standard is effective for fiscal years beginning 
after December 15, 2016, including interim periods within that reporting period. Early adoption is 
permitted for any interim and annual financial statements that have not yet been issued. Effective 
December 31, 2015, the Company early adopted the deferred tax standard retrospectively, as a change in 
accounting principle. The impact of this change on the Company's prior years Consolidated Balance 
Sheets and Consolidated Statements of Cash Flows is shown in the table below. The adoption of this 
standard had no impact on our results of operations.

In April 2015, the FASB issued a new standard related to the presentation of debt issuance costs ("debt 
issuance costs standard"). The debt issuance cost standard requires debt issuance costs related to 
recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount 
of that debt liability, consistent with debt discounts. The previous standard required these debt issuance 
costs be classified as an asset and amortized ratably over the life of the debt. The debt issuance cost 
standard is effective for fiscal years beginning after December 15, 2015, including interim periods within 
that reporting period. Early adoption is permitted for any interim and annual financial statements that have 

57

not yet been issued. The Company has elected to early adopt the debt issuance costs standard, effective 
December 31, 2015. The adoption of the debt issuance costs standard had no impact on our results of 
operations. This guidance is effective on a retrospective basis, as a change in accounting principle. The 
impact of this change on the Company's prior years Consolidated Balance Sheets and Consolidated 
Statements of Cash Flows is shown in the table below.

In April 2014, the FASB issued new accounting guidance which changes the criteria for reporting 
discontinued operations and enhances disclosures in this area. Under the new guidance, only disposals 
representing a strategic shift in operations, such as disposal of a major geographic area or a major line of 
business, should be presented as discontinued operations. Those strategic shifts should have a major 
impact on the organization's operations and financial results. In addition, the new guidance requires 
expanded disclosures about discontinued operations. The guidance is effective for fiscal years beginning 
on or after December 15, 2014. Adoption of the guidance did not have a material affect on the Company's 
financial condition, results of operations or cash flows.

Reclassifications

In addition to the above changes, reclassifications have been made to prior period amounts to conform 
with current year separate presentation of goodwill and other intangible assets in the consolidated 
balance sheets.

4.     Acquisitions / Dispositions

The Company’s acquisitions have been accounted for as business combinations. Net assets and results 
of operations are included in the Company’s consolidated financial statements commencing at the 
respective purchase closing dates. In connection with acquisitions, the Company records the estimated 
value of the net tangible assets purchased and the value of the identifiable intangible assets purchased, 
which typically consist of purchased customer lists, trademarks and non-compete agreements. The 
valuation of purchased intangible assets involves significant estimates and assumptions. Any change in 
assumptions could affect the carrying value of such intangible assets.

Total purchase consideration for acquisitions made during 2015 was approximately $1.2 billion, which 
consisted of cash paid of $1.0 billion and deferred purchase and estimated contingent consideration of 
$176 million. Contingent consideration arrangements are based primarily on EBITDA and revenue targets 
over periods of two to four years. The fair value of the contingent consideration was based on projected 
revenue and earnings of the acquired entities. Estimated fair values of assets acquired and liabilities 
assumed are subject to adjustment when purchase accounting is finalized. During 2015, the Company 
also paid $36 million of deferred purchase consideration and $47 million of contingent consideration 
related to acquisitions made in prior years. In addition, the Company purchased other intangible assets in

Pro-Forma Information

While the Company does not believe its acquisitions in the aggregate are material, the following 
unaudited pro-forma financial data gives effect to the acquisitions made by the Company during 2015 and 
2014. In accordance with accounting guidance related to pro-forma disclosures, the information 
presented for current year acquisitions is as if they occurred on January 1, 2014 and reflects acquisitions 
made in 2014 as if they occurred on January 1, 2013. The pro-forma information adjusts for the effects of 
amortization of acquired intangibles. The unaudited pro-forma financial data is presented for illustrative 
purposes only and is not necessarily indicative of the operating results that would have been achieved if 
such acquisitions had occurred on the dates indicated, nor is it necessarily indicative of future

The consolidated statement of income for 2015 includes approximately $124 million of revenue and $7 
million of operating income related to acquisitions made during 2015.

Dispositions

In December 2015, Mercer sold its U.S. defined contribution recordkeeping business, recognizing a pre-
tax gain of $37 million, which is included in revenue in the consolidated statements of income. The sale 
agreement includes contingent consideration based on retention and renewal of the client contracts by 
the acquirer. Additional consideration, if any, will be recognized when all conditions precedent to its 
receipt have been satisfied.

5.     Discontinued Operations

As part of the disposal transactions for Putnam and Kroll, the Company provided certain indemnities, 
primarily related to pre-transaction tax uncertainties and legal contingencies. In accordance with 
applicable accounting guidance, liabilities were established related to these indemnities at the time of the 
sales and reflected as a reduction of the gain on disposal. Discontinued operations includes charges or 
credits resulting from the settlement or resolution of the indemnified matters, as well as adjustments to the 
liabilities related to such matters.

On December 31, 2014, an agreement was reached between Putnam and the Massachusetts 
Department of Revenue ("DOR") regarding a tax dispute, which was covered under the indemnity 
agreement discussed above. The December 2014 agreement was subject to certain approvals, which 
included the State Attorney General and the Commissioner of the DOR. In January 2015, all necessary 
approvals were received, the agreement was executed and the tax was paid. Concurrently, Putnam and 
the Company executed a settlement agreement to resolve all remaining matters under the indemnity 
agreement. The Company recorded a gain, net of federal income taxes, of approximately $28 million in 
2014 related to the settlement with Putnam.

Discontinued operations in 2013 includes estimated costs covered under the indemnity related to the Kroll 
sale as well as tax indemnities related to the Putnam sale.

6.    Goodwill and Other Intangibles

The Company is required to assess goodwill and any indefinite-lived intangible assets for impairment 
annually, or more frequently if circumstances indicate impairment may have occurred. The Company 
performs the annual impairment assessment for each of its reporting units during the third quarter of each 
year. In accordance with applicable accounting guidance, the Company assesses qualitative factors to 
determine whether it is necessary to perform the two-step goodwill impairment test. The Company 
considered numerous factors, which included that the fair value of each reporting unit exceeded its 
carrying value by a substantial margin in its most recent estimate of reporting unit fair values, whether 
significant acquisitions or dispositions occurred which might alter the fair value of its reporting units, 
macroeconomic conditions and their potential impact on reporting unit fair values, actual performance 
compared with budget and prior projections used in its estimation of reporting unit fair values, industry 
and market conditions, and the year-over-year change in the Company’s share price. The Company 
completed its qualitative assessment in the third quarter of 2015 and concluded that a two-step goodwill 
impairment test was not required in 2015 and that goodwill was not impaired.

Other intangible assets that are not deemed to have an indefinite life are amortized over their estimated 
lives and reviewed for impairment upon the occurrence of certain triggering events in accordance with 
applicable accounting literature.

purposes) is comprised of $639 million related to the Risk and Insurance Services segment and $144 
million related to the Consulting segment.

Goodwill allocable to the Company’s reportable segments is as follows: Risk and Insurance Services,

U.S. Federal income taxes are not provided on the excess of the amount for financial reporting over the 
tax basis of investments in foreign subsidiaries that are essentially permanent in duration, which at 
December 31, 2015, the Company estimates, amounted to approximately $3.4 billion. The determination 
of the unrecognized deferred tax liability with respect to these investments is not practicable.

A reconciliation from the U.S. Federal statutory income tax rate to the Company’s effective income tax 
rate is shown below:

The Company’s consolidated tax rate was 29.1%, 28.5% and 30.1% in 2015, 2014 and 2013, 
respectively. The tax rate in each year reflects foreign operations, which are generally taxed at rates lower 
than the U.S. statutory tax rate.

Valuation allowances had a net decrease of $69 million in 2015, and net increases of $15 million and $10 
million in 2014 and 2013, respectively. During the respective years, adjustments of the beginning of the 
year balances of valuation allowances decreased income tax expense by $14 million, $9 million and $3 
million in 2015, 2014 and 2013, respectively. The decrease in the valuation allowance in 2015 also 
reflects the write down of a deferred tax asset along with its full valuation allowance because the 
Company cannot utilize a net operating loss. Approximately 80% of the Company’s net operating loss 
carryforwards expire from 2016 through 2035, and others are unlimited. The potential tax benefit from net 
operating loss carryforwards at the end of 2015 comprised federal, state and local, and non-U.S. tax 
benefits of $10 million, $55 million and $36 million, respectively, before reduction for valuation allowances. 
Foreign tax credit carryforwards expire in 2021 and 2022.

The realization of deferred tax assets depends on generating future taxable income during the periods in 
which the tax benefits are deductible or creditable. Tax liabilities are determined and assessed 
jurisdictionally by legal entity or filing group. Certain taxing jurisdictions allow or require combined or 
consolidated tax filings. The Company assessed the realizability of its deferred tax assets and 
considered all available evidence, including the existence of a recent history of losses, placing particular 
weight on evidence that could be objectively verified. A valuation allowance was recorded to reduce 
deferred tax assets to the amount that the Company believes is more likely than not to be realized.

Following is a reconciliation of the Company’s total gross unrecognized tax benefits for the years ended 
December 31, 2015, 2014 and 2013:

Of the total unrecognized tax benefits at December 31, 2015, 2014 and 2013, $53 million, $51 million and 
$71 million, respectively, represent the amount that, if recognized, would favorably affect the effective tax 
rate in any future periods. The total gross amount of accrued interest and penalties at December 31, 
2015, 2014 and 2013, before any applicable federal benefit, was $8 million, $7 million and $10 million, 
respectively.

As discussed in Note 5, the Company has provided certain indemnities related to contingent tax liabilities 
as part of the disposals of Putnam and Kroll. At December 31, 2015, 2014 and 2013, $1 million, $2 million 
and $2 million, respectively, included in the table above, relates to Putnam and Kroll positions included in 
consolidated Company tax returns. Since the Company remains primarily liable to the taxing authorities 
for resolution of uncertain tax positions related to consolidated returns, these balances will remain as part 
of the Company’s consolidated liability for uncertain tax positions. Any future charges or credits related to 
these matters, including interest accrued, will be recorded in discontinued operations as incurred.

The Company is routinely examined by the jurisdictions in which it has significant operations. In the U.S. 
federal jurisdiction the Company participates in the Internal Revenue Service’s (IRS) Compliance 
Assurance Process (CAP), which is structured to conduct real-time compliance reviews. The IRS is 
currently examining the Company’s 2014 tax return and performing a pre-filing review of 2015. During 
2015 the Company settled its federal tax audit with the IRS for the year 2013. In 2014, the Company 
settled its federal tax audit for the year 2012, and in 2013 settled the years 2007, and 2009 through 2011.  
The tax year 2008 was settled in a prior period. New York State and New York City have examinations 
underway for various entities covering the years 2007 through 2014. During 2015, Illinois completed its 
audit of years 2009 through 2010. Outside the United States, during calendar year 2015 examinations 
commenced in Germany for the years 2009 through 2012. There are ongoing examinations of certain 
subsidiaries in France for years 2011 to 2014, in Canada for years 2012 and 2013 and in the United 
Kingdom for years 2011 and 2012, as well as in other smaller jurisdictions. The Company regularly 
considers the likelihood of assessments in each of the taxing jurisdictions resulting from examinations. 
The Company has established liabilities for uncertain tax positions in relation to the potential 
assessments. The Company believes the resolution of tax matters will not have a material effect on the 
consolidated financial position of the Company, although a resolution of tax matters could have a material 
impact on the Company's net income or cash flows and on its effective tax rate in a particular future 
period. It is reasonably possible that the total amount of unrecognized tax benefits will decrease between 
zero and approximately $8 million within the next twelve months due to the settlement of audits and the 
expiration of statutes of limitation.

8.    Retirement Benefits

The Company maintains qualified and non-qualified defined benefit pension plans for its U.S. and non-
U.S. eligible employees. The Company’s policy for funding its tax qualified defined benefit retirement 
plans is to contribute amounts at least sufficient to meet the funding requirements set forth by U.S. law 
and the laws of the non-U.S. jurisdictions in which the Company offers defined benefit plans.

Combined U.S. and non-U.S. Plans

The weighted average actuarial assumptions utilized for the U.S. and significant non-U.S. defined benefit 
plans and postretirement benefit plans are as follows:

The Company uses actuaries from Mercer, a subsidiary of the Company, to perform valuations of its 
pension plans. The long-term rate of return on plan assets assumption is determined for each plan based 
on the facts and circumstances that exist as of the measurement date, and the specific portfolio mix of 
each plan’s assets. The Company utilizes a model developed by the Mercer actuaries to assist in the 
determination of this assumption. The model takes into account several factors, including: actual and 
target portfolio allocation; investment, administrative and trading expenses incurred directly by the plan 
trust; historical portfolio performance; relevant forward-looking economic analysis; and expected returns, 
variances and correlations for different asset classes. These measures are used to determine 
probabilities using standard statistical techniques to calculate a range of expected returns on the portfolio. 
The Company generally does not adjust the rate of return assumption from year to year if, at the 
measurement date, it is within the range between the 25th and 75th percentile of the expected long-term 
annual returns. Historical long-term average asset returns of each plan are also reviewed to determine 
whether they are consistent and reasonable compared with the rate selected. The expected return on 
plan assets is determined by applying the assumed long-term rate of return to the market-related value of 
plan assets. This market-related value recognizes investment gains or losses over a five-year period from 
the year in which they occur. Investment gains or losses for this purpose are the difference between the 
expected return calculated using the market-related value of assets and the actual return based on the 
market value of assets. Since the market-related value of assets recognizes gains or losses over a five-
year period, the future market-related value of the assets will be impacted as previously deferred gains or 
losses are reflected.

The target asset allocation for the U.S. Plans is 64% equities and equity alternatives and 36% fixed 
income. At the end of 2015, the actual allocation for the U.S. Plans was 63% equities and equity 
alternatives and 37% fixed income. The target asset allocation for the U.K. Plans, which comprise 
approximately 83% of non-U.S. Plan assets, is 48% equities and equity alternatives and 52% fixed 
income.  At the end of 2015, the actual allocation for the U.K. Plans was 47% equities and equity 
alternatives and 53% fixed income. The assets of the Company's defined benefit plans are diversified and 
are managed in accordance with applicable laws and with the goal of maximizing the plans' real return 
within acceptable risk parameters. The Company uses threshold-based portfolio re-balancing to ensure 
the actual portfolio remains consistent with target asset allocation ranges.

The discount rate selected for each U.S. plan is based on a model bond portfolio with coupons and 
redemptions that closely match the expected liability cash flows from the plan. Discount rates for non-U.S. 
plans are based on appropriate bond indices adjusted for duration; in the U.K., the plan duration is 
reflected using the Mercer yield curve.

The components of the net periodic benefit cost for defined benefit and other postretirement plans are as 
follows:

Plan Assets

For the U.S. Plans, investment allocation decisions are made by a fiduciary committee composed of 
senior executives appointed by the Company’s Chief Executive Officer. For the non-U.S. plans, 
investment allocation decisions are made by local fiduciaries, in consultation with the Company for the 
larger plans. Plan assets are invested in a manner consistent with the fiduciary standards set forth in all 
relevant laws relating to pensions and trusts in each country. Primary investment objectives are (1) to 
achieve an investment return that, in combination with current and future contributions, will provide 
sufficient funds to pay benefits as they become due, and (2) to minimize the risk of large losses. The 
investment allocations are designed to meet these objectives by broadly diversifying plan assets among 
numerous asset classes with differing expected returns, volatilities, and correlations.

The major categories of plan assets include equity securities, equity alternative investments, and fixed 
income securities. For the U.S. qualified plans, the category ranges are 59-69% for equities and equity 
alternatives, and 31-41% for fixed income. For the U.K. Plan, the category ranges are 45-51% for equities 
and equity alternatives, and 49-55% for fixed income. Asset allocation is monitored frequently and re-
balancing actions are taken as appropriate. Re-balancing in the U.K. Plan was suspended in 2014 while a 
contingent guarantee agreement was put in place and the investment strategy of the plan was finalized. 
After the contingent guarantee agreement was executed in January 2015, re-balancing resumed in 
February 2015 with target asset allocation of 48% equities and equity alternatives and 52% fixed income.

Plan investments are exposed to stock market, interest rate, and credit risk. Concentrations of these risks 
are generally limited due to diversification by investment style within each asset class, diversification by 
investment manager, diversification by industry sectors and issuers, and the dispersion of investments 
across many geographic areas.

Unrecognized Actuarial Gains/Losses

In accordance with applicable accounting guidance, the funded status of the Company's pension plans is 
recorded in the consolidated balance sheets and provides for a delayed recognition of actuarial gains or 
losses arising from changes in the projected benefit obligation due to changes in the assumed discount 
rates, differences between the actual and expected value of plan assets and other assumption changes.  
The unrecognized pension plan actuarial gains or losses and prior service costs not yet recognized in net 
periodic pension cost are recognized in Accumulated Other Comprehensive Income ("AOCI"), net of tax. 
These gains and losses are amortized prospectively out of AOCI over a period that approximates the 
average remaining service period of active employees, or for plans in which substantially all the 
participants are inactive, over the remaining life expectancy of the inactive employees.

Interest and Service Cost

In 2016, the Company changed the approach used to estimate the service and interest cost components 
of net periodic benefit cost for its significant non-U.S. plans. Historically, service and interest costs were 
estimated using a single weighted average discount rate derived from the yield curves used to measure 
the benefit obligations at the beginning of the period. This change in approach was made to improve the 
correlation between the projected benefit cash flows and the corresponding yield curve spot rates and to 
provide a more precise measurement of service and interest costs. The change does not impact the 
measurement of the plans’ total Projected Benefit Obligation. The Company has accounted for this 
change as a change in estimate, that will be applied prospectively beginning in 2016. As a result of this 
change, service and interest cost in 2016 are expected to be approximately $45 million lower than if the 
prior methodology were used in 2016.

In 2014, the Society of Actuaries in the United States issued a new mortality table (RP-2014) and an 
updated improvement scale. The Company considered the effect of RP-2014, along with other available 
information on mortality improvement and industry specific mortality studies, to select its assumptions for 
measurement of the plans’ benefit obligations at December 31, 2014 and 2015.

The projected benefit obligation, accumulated benefit obligation and aggregate fair value of plan assets 
for U.S. pension plans with accumulated benefit obligations in excess of plan assets were $5.7 billion, 
$5.6 billion and $4.2 billion, respectively, as of December 31, 2015 and $5.9 billion, $5.8 billion and $4.5 
billion, respectively, as of December 31, 2014. 

The projected benefit obligation and fair value of plans assets for U.S. pension plans with projected 
benefit obligations in excess of plan assets was $5.7 billion and $4.2 billion, respectively, as of 
December 31, 2015 and $5.9 billion and $4.5 billion, respectively, as of December 31, 2014.

As of December 31, 2015, the U.S. qualified plans hold 4 million shares of the Company’s common stock 
which were contributed to the Plan by the Company in 2005. This represented approximately 5.3% of 
those plans' assets as of December 31, 2015. In addition, plan assets may be invested in funds managed 
by Mercer Investments, a subsidiary of the Company.

Effective September 1, 2015, the Company divided its U.S. qualified defined benefit plan to provide 
enhanced flexibility and better manage the risks. The existing plan was amended to cover only the 
retirees currently receiving benefits and terminated vested participants as of August 1, 2015. The 
Company's active participants as of that date were transferred into a newly established, legally separate 
qualified defined benefit plan. The benefits offered to the plans’ participants were unchanged. As a result 
of the plan amendment and establishment of the new plan, the Company re-measured the assets and 
liabilities of the two plans as required under U.S. GAAP, based on assumptions and market conditions at 
the amendment date. The net periodic pension expense recognized in 2015 reflects the weighted average 
costs of the December 31, 2014 measurement and the September 1, 2015 re-measurement.

75

In March 2015, the Company amended its U.S. Post-65 retiree medical reimbursement plan (the "RRA 
plan"), resulting in its termination, with benefits to certain participants paid through December 31, 2016. 
As a result of the termination of the RRA plan, the Company recognized a net credit of approximately 
$125 million in the first quarter of 2015.

In December 2003, the Medicare Prescription Drug, Improvement and Modernization Act of 2003 became 
law. The net periodic benefit cost for all periods shown above includes the related subsidy.

The assumed health care cost trend rate for Medicare eligibles and non-Medicare eligibles is 
approximately 7.3% in 2015, gradually declining to 4.5% in 2029. Assumed health care cost trend rates 
have a small effect on the amounts reported for the U.S. health care plans because the Company caps its 
share of health care trend at 5%. A one percentage point change in assumed health care cost trend rates 
would have no effect on the total service and interest cost components or the postretirement benefit 
obligation.

Estimated Future Contributions

The Company expects to fund approximately $26 million for its U.S. non-qualified plans in 2016. The 
Company’s policy for funding its tax-qualified defined benefit retirement plans is to contribute amounts at 
least sufficient to meet the funding requirements set forth in the U.S. and applicable foreign law. There is 
currently no ERISA funding requirement for the U.S. qualified plans for 2016.

The non-U.S. defined benefit plans do not have any direct ownership of the Company’s common stock.

The pension plan in the United Kingdom no longer holds an interest in the Trident III private equity fund, 
since the fund fully harvested all its portfolio investments and made final distributions to its partners in 
2015.

The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the non-
U.S. pension plans with accumulated benefit obligations in excess of plan assets were $1.7 billion, $1.6 
billion and $1.3 billion, respectively, as of December 31, 2015 and $2.1 billion, $2.0 billion and $1.6 billion, 
respectively, as of December 31, 2014.

The projected benefit obligation and fair value of plan assets for non-U.S. pension plans with projected 
benefit obligations in excess of plan assets was $1.9 billion and $1.5 billion, respectively, as of 
December 31, 2015 and $2.2 billion and $1.6 billion, respectively, as of December 31, 2014.

Non-U.S. Plan Amendments

Effective August 1, 2015, the Company amended its Ireland defined benefit pension plans to close those 
plans to future benefit accruals and replaced those plans with a defined contribution arrangement. The 
Company re-measured the assets and liabilities of the plans, based on assumptions and market 
conditions on the amendment date. The net periodic pension costs recognized in 2015 reflects the 
weighted average costs of the December 31, 2014 measurement and the August 1, 2015 re-
measurement.

After completion of a consultation period with affected colleagues, in January 2014, the Company 
amended its U.K. defined benefit pension plans to close those plans to future benefit accruals effective 
August 1, 2014 and replaced those plans, along with its existing defined contribution plans, with a new, 
comprehensive defined contribution arrangement. This change resulted in a curtailment of the U.K. 
defined benefit plans and, as required under GAAP, the Company re-measured the defined benefit plans’ 
assets and liabilities at the amendment date, based on assumptions and market conditions at that date. 
The net periodic benefit costs recognized in 2014 are the weighted average resulting from the 
December 31, 2013 measurement and the January 2014 re-measurement. The Company recognized a 
curtailment gain of $65 million in the first quarter of 2014, primarily resulting from the recognition of the 
remaining unamortized prior service credit related to a plan amendment made in December 2012. This 
gain was mostly offset by the cost of a transition benefit for certain employees most impacted by the 
amendment, which is not part of net periodic pension cost.

Components of Net Periodic Benefits Costs

The assumed health care cost trend rate was approximately 5.30% in 2015, gradually declining to 4.53% 
in 2026. Assumed health care cost trend rates can have a significant effect on the amounts reported for 
the non-U.S. health care plans. A one percentage point change in assumed health care cost trend rates 
would have the following effects:

(In millions of dollars)
Effect on total of service and interest cost components

The Company expects to fund approximately $191 million to its non-U.S. pension plans in 2016. Funding 
requirements for non-U.S. plans vary by country. Contribution rates are generally based on local funding 
practices and requirements, which may differ significantly from measurements under U.S. GAAP.  
Funding amounts may be influenced by future asset performance, the level of discount rates and other 
variables impacting the assets and/or liabilities of the plan. Discretionary contributions may also be 
affected by alternative uses of the Company’s cash flows, including dividends, investments and share 
repurchases.

In the U.K., contributions to defined benefit pension plans are determined through a negotiation process 
between the Company and the plans' Trustee that typically occurs every three years in conjunction with 
the actuarial valuation of the plans. This process is governed by U.K. pension regulations. The 
assumptions that result from the funding negotiations are different from those used for U.S. GAAP and 
currently result in a lower funded status than under U.S. GAAP. In March 2014, the Company and the 
Trustee of the U.K. Defined Benefits Plans agreed to a funding deficit recovery plan for the U.K. defined 
benefit pension plans. The current agreement with the Trustee sets out the annual deficit contributions 
which would be due based on the deficit at December 31, 2012. The funding level is subject to re-
assessment, in most cases on November 1st of each year. If the funding level on November 1st has 
sufficiently improved, no deficit funding contributions will be required in the following year, and the 
contribution amount will be deferred. As part of a long-term strategy, which depends on having greater 
influence over asset allocation and overall investment decisions, the Company has agreed to support 
annual deficit contributions by the U.K. operating companies under certain circumstances, up to GBP 450 
million over a seven-year period.

Defined Benefit Plans Fair Value Disclosures

In December 2008, the FASB issued guidance for Employers’ Disclosures About Pension and Other Post 
Retirement Benefit Plan Assets. The guidance requires fair value plan asset disclosures for an employer’s 
defined benefit pension and postretirement plans similar to the guidance on Fair Value Measurements as 
well as (a) how investment allocation decisions are made, (b) the major categories of plan assets, and 
(c) significant concentrations of risk within plan assets.

The U.S. and non-U.S. plan investments are classified into Level 1, which refers to investments valued 
using quoted prices from active markets for identical assets; Level 2, which refers to investments not 
traded on an active market but for which observable market inputs are readily available; and Level 3, 
which refers to investments valued based on significant unobservable inputs. Assets and liabilities are 
classified in their entirety based on the lowest level of input that is significant to the fair value 
measurement.

81

The following table sets forth, by level within the fair value hierarchy, a summary of the U.S. and non-U.S. 
plans' investments measured at fair value on a recurring basis at December 31, 2015 and 2014:

The following is a description of the valuation methodologies used for assets measured at fair value:

Company common stock:  Valued at the closing price reported on the New York Stock Exchange.

Common stocks, preferred stocks, convertible equity securities and rights/warrants (included in Corporate 
stocks):  Valued at the closing price reported on the primary exchange.

Corporate bonds (included in Corporate obligations):  The fair value of corporate bonds is estimated using 
recently executed transactions, market price quotations (where observable) and bond spreads. The 
spread data used are for the same maturity as the bond. If the spread data does not reference the issuer, 
then data that references a comparable issuer are used. When observable price quotations are not 
available, fair value is determined based on cash flow models.

Commercial mortgage-backed and asset-backed securities (included in Corporate obligations):  Fair 
value is determined using discounted cash flow models. Observable inputs are based on trade and quote 
activity of bonds with similar features including issuer vintage, purpose of underlying loan (first or second 
lien), prepayment speeds and credit ratings. The discount rate is the combination of the appropriate rate 
from the benchmark yield curve and the discount margin based on quoted prices.

Common/Collective trusts:  Valued at the net asset value of units of a bank collective trust. The net asset 
value as provided by the trustee, is used as a practical expedient to estimate fair value. The net asset 
value is based on the fair value of the underlying investments held by the fund less its liabilities. This 
practical expedient is not used when it is determined to be probable that the fund will sell the investment 
for an amount different than the reported net asset value. 

83

U.S. government bonds (included in Government securities):  The fair value of U.S. government bonds is 
estimated by pricing models that utilize observable market data including quotes, spreads and data points 
for yield curves.

U.S. agency securities (included in Government securities):  U.S. agency securities are comprised of two 
main categories consisting of agency issued debt and mortgage pass-throughs. Agency issued debt 
securities are valued by benchmarking market-derived prices to quoted market prices and trade data for 
identical or comparable securities. Mortgage pass-throughs include certain "To-be-announced" (TBA) 
securities and mortgage pass-through pools. TBA securities are generally valued using quoted market 
prices or are benchmarked thereto. Fair value of mortgage pass-through pools are model driven with 
respect to spreads of the comparable TBA security.

Private equity and real estate partnerships:  Investments in private equity and real estate partnerships are 
valued based on the fair value reported by the manager of the corresponding partnership and reported on 
a one quarter lag. The managers provide unaudited quarterly financial statements and audited annual 
financial statements which set forth the value of the fund. The valuations obtained from the managers are 
based on various analyses on the underlying holdings in each partnership, including financial valuation 
models and projections, comparable valuations from the public markets, and precedent private market 
transactions. Investments are valued in the accompanying financial statements based on the Plan’s 
beneficial interest in the underlying net assets of the partnership as determined by the partnership 
agreement.

Insurance group annuity contracts:  The fair values for these investments are based on the current market 
value of the aggregate accumulated contributions plus interest earned.

Swap assets (included in Other investments):  Fair values for interest rate swaps, equity index swaps and 
inflation swaps are estimated using a discounted cash flow pricing model. These models use observable 
market data such as contractual fixed rate, broker quotes, spot equity price or index value and dividend 
data. The fair values of credit default swaps are estimated using an income approach model which 
determines expected cash flows based on default probabilities from the issuer-specific credit spread 
curve and credit loss recovery rates, both of which are dependent on market quotes.

Real estate investment trusts (included in Corporate stocks):  Valued at the closing price reported on an 
exchange.

Short-term investment funds:  Primarily high-grade money market instruments valued at net asset value 
at year-end.

Real estate:  Valued by investment managers generally using proprietary pricing models.

Registered investment companies:  Valued at the closing price reported on the primary exchange.

Defined Contribution Plans

The Company maintains certain defined contribution plans for its employees, including the Marsh & 
McLennan Companies 401(k) Savings & Investment Plan ("401(k) Plan"), that are qualified under U.S. tax 
laws. Under these plans, eligible employees may contribute a percentage of their base salary, subject to 
certain limitations. For the 401(k) Plan, the Company matches a fixed portion of the employees’ 
contributions. The 401(k) Plan contains an Employee Stock Ownership Plan feature under U.S. tax law.  
Approximately $398 million of the 401(k) Plan’s assets at December 31, 2015 and $453 million  in 
December 31, 2014 were invested in the Company’s common stock. If a participant does not choose an 
investment direction for his or her future contributions, they are automatically invested in a BlackRock 
LifePath Portfolio that most closely matches the participant’s expected retirement year. The cost of these 
defined contribution plans was $51 million in 2015, $49 million in 2014 and $50 million in 2013. In 
addition, the Company has a significant defined contribution plan in the U.K. As noted above, effective 
August 1, 2014, a newly formed defined contribution plan replaced the existing defined contribution and 
defined benefit plans with regard to future service. The cost of the U.K. defined contribution plan was $93 
million, $65 million and $23 million in 2015, 2014 and 2013, respectively.

Stock Benefit Plans 

The Company maintains multiple stock-based payment arrangements under which employees are 
awarded grants of restricted stock units, stock options and other forms of stock-based payment 
arrangements.   

Marsh & McLennan Companies, Inc. Incentive and Stock Award Plans

On May 19, 2011, the Marsh & McLennan Companies, Inc. 2011 Incentive and Stock Award Plan (the 
"2011 Plan") was approved by the Company's stockholders. The 2011 Plan replaced the Company's two 
previous equity incentive plans (the 2000 Senior Executive Incentive and Stock Award Plan and the 2000 
Employee Incentive and Stock Award Plan).

The types of awards permitted under the 2011 Plan include stock options, restricted stock and restricted 
stock units payable in Company common stock or cash, and other stock-based and performance-based 
awards. The Compensation Committee of the Board of Directors (the "Compensation Committee") 
determines, at its discretion, which affiliates may participate in the 2011 Plan, which eligible employees 
will receive awards, the types of awards to be received, and the terms and conditions thereof. The right of 
an employee to receive an award may be subject to performance conditions as specified by the 
Compensation Committee. The 2011 Plan contains a provision which, in the event of a change in control 
of the Company, may accelerate the vesting of the awards. This provision requires both a change in 
control of the Company and a subsequent specified termination of employment for vesting to be 
accelerated.

The 2011 Plan retains the remaining share authority of the two previous plans as of the date the 2011 
Plan was approved by stockholders. Thus, approximately 23.2 million shares of common stock, plus 
shares remaining unused under the previous plans, are available for awards over the life of the 2011 
Plan.

The current practice is to grant non-qualified stock options, restricted stock units and/or performance 
stock units ("PSUs") on an annual basis to senior executives and a limited number of other employees as 
part of their total compensation. Restricted stock units are also granted to new hires or as retention 
awards for certain employees. Restricted stock has not been granted since 2005.

Stock Options:  Options granted under the 2011 Plan may be designated as either incentive stock options 
or non-qualified stock options. The Compensation Committee determines the terms and conditions of the 
option, including the time or times at which an option may be exercised, the methods by which such 
exercise price may be paid, and the form of such payment. Options are generally granted with an 
exercise price equal to the market value of the Company's common stock on the date of grant. These 
option awards generally vest 25% per annum and have a contractual term of 10 years.

The estimated fair value of options granted is calculated using the Black-Scholes option pricing valuation 
model. This model takes into account several factors and assumptions. The risk-free interest rate is 
based on the yield on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life 
assumption at the time of grant. The expected life (estimated period of time outstanding) is estimated 
using the contractual term of the option and the effects of employees' expected exercise and post-vesting 
employment termination behavior. The Company uses a blended volatility rate based on the following: (i) 
volatility derived from daily closing price observations for the 10-year period ended on the valuation date, 
(ii) implied volatility derived from traded options for the period one week before the valuation date and (iii) 
average volatility for the 10-year periods ended on 15 anniversaries prior to the valuation date, using daily 
closing price observations. The expected dividend yield is based on expected dividends for the expected 
term of the stock options.

85

The assumptions used in the Black-Scholes option pricing valuation model for options granted by the 
Company in 2015, 2014 and 2013 are as follows:

Expected life (in years)
Expected volatility

In the above table, forfeited options are unvested options whose requisite service period has not been 
met. Expired options are vested options that were not exercised. The weighted-average grant-date fair 
value of the Company's option awards granted during the years ended December 31, 2015, 2014 and 
2013 was $11.34, $9.66 and $6.21, respectively. The total intrinsic value of options exercised during the 
same periods was $124.6 million, $174.3 million and $198.1 million, respectively.

As of December 31, 2015, there was $11.8 million of unrecognized compensation cost related to the 
Company's option awards. The weighted-average period over which that cost is expected to be 
recognized is approximately 1.16 years. Cash received from the exercise of stock options for the years 
ended December 31, 2015, 2014 and 2013 was $134.7 million, $178.1 million and $281.1 million, 
respectively.

The Company's policy is to issue treasury shares upon option exercises or share unit conversion. The 
Company intends to issue treasury shares as long as an adequate number of those shares is available.

Restricted Stock Units and Performance Stock Units: Restricted stock units may be awarded under the 
Company's 2011 Incentive and Stock Award Plan. The Compensation Committee determines the 
restrictions on such units, when the restrictions lapse, when the units vest and are paid, and under what 
terms the units are forfeited. The cost of these awards is amortized over the vesting period, which is 
generally three years. Awards to senior executives and other employees may include three-year 
performance-based restricted stock units and three-year service-based restricted stock units. The payout 
of performance stock units (payable in shares of the Company's common stock) ranges, generally, from 
0-200% of the number of units granted, based on the achievement of objective, pre-determined Company 
performance measures, generally, over a three-year performance period. The Company accounts for 
these awards as performance condition restricted stock units. The performance condition is not 
considered in the determination of grant date fair value of such awards. Compensation cost is recognized 
over the performance period based on management's estimate of the number of units expected to vest 
and is adjusted to reflect the actual number of shares paid out at the end of the three-year performance 
period. Dividend equivalents are not paid out unless and until such time that the award vests.

non-option equity awards was $114.3 million, $165.3 million and $205.5 million, respectively.

The payout of shares in respect of PSUs awarded in 2012 that vested in 2015 on the PSU Scheduled 
Vesting Date was 200% of target. The payout of shares in respect of PSUs awarded in 2013 and 2014 
that vested in 2015 (either in full or on a pro-rata basis due to certain types of termination) was 200% and 
167% of target, respectively. In aggregate, 746,370 shares became distributable in respect to PSUs 
vested in 2015.

Restricted Stock:  Restricted shares of the Company's common stock may be awarded under the 2011 
Plan and are subject to restrictions on transferability and other restrictions, if any, as the Compensation 
Committee may impose. The Compensation Committee may also determine when and under what 
circumstances the restrictions may lapse and whether the participant receives the rights of a stockholder, 
including, without limitation, the right to vote and receive dividends. Unless the Compensation Committee 
determines otherwise, restricted stock that is still subject to restrictions is forfeited upon termination of 
employment. There have been no restricted shares granted since 2005.

Marsh & McLennan Companies Stock Purchase Plans

In May 1999, the Company's stockholders approved an employee stock purchase plan (the "1999 Plan") 
to replace the 1994 Employee Stock Purchase Plan (the "1994 Plan"), which terminated on September 
30, 1999 following its fifth annual offering. Under the current terms of the Plan, shares are purchased four 
times during the plan year at a price that is 95% of the average market price on each quarterly purchase 
date. Under the 1999 Plan, after including the available remaining unused shares in the 1994 Plan and 
reducing the shares available by 10,000,000 consistent with the Company's Board of Directors' action in 
March 2007, no more than 35,600,000 shares of the Company's common stock may be sold. Employees 
purchased 507,411 shares during the year ended December 31, 2015 and at December 31, 2015, 
2,271,784 shares were available for issuance under the 1999 Plan. Under the 1995 Company Stock 
Purchase Plan for International Employees (the "International Plan"), after reflecting the additional 
5,000,000 shares of common stock for issuance approved by the Company's Board of Directors in July 
2002, and the addition of 4,000,000 shares due to a shareholder action in May 2007, no more than 
12,000,000 shares of the Company's common stock may be sold. Employees purchased 145,422 shares 
during the year ended December 31, 2015 and there were 2,748,564 shares available for issuance at 
December 31, 2015 under the International Plan. The plans are considered non-compensatory.

10.     Fair Value Measurements

Fair Value Hierarchy

The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis 
into a three-level fair value hierarchy as defined by the accounting literature. The fair value hierarchy 
gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and 
lowest priority to unobservable inputs (Level 3). In some cases, the inputs used to measure fair value 
might fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, 
for disclosure purposes, is determined based on the lowest level input that is significant to the fair value 
measurement. Assets and liabilities recorded in the consolidated balance sheets at fair value are 
categorized based on the inputs in the valuation techniques as follows:

Level 1. 

Assets and liabilities whose values are based on unadjusted quoted prices for identical 
assets or liabilities in an active market (examples include active exchange-traded equity 
securities and money market mutual funds).

Assets and liabilities utilizing Level 1 inputs include exchange-traded mutual funds and money market 
funds.

Level 2. 

Assets and liabilities whose values are based on the following:

a) 

b) 

c) 

d) 

Quoted prices for similar assets or liabilities in active markets;

Quoted prices for identical or similar assets or liabilities in non-active markets 
(examples include corporate and municipal bonds, which trade infrequently);

Pricing models whose inputs are observable for substantially the full term of the 
asset or liability (examples include most over-the-counter derivatives, including 
interest rate and currency swaps); and

Pricing models whose inputs are derived principally from or corroborated by 
observable market data through correlation or other means for substantially the 
full asset or liability (for example, certain mortgage loans).

The Company does not have any assets or liabilities that utilize Level 2 inputs. 

88

Level 3. 

Assets and liabilities whose values are based on prices, or valuation techniques that 
require inputs that are both unobservable and significant to the overall fair value 
measurement. These inputs reflect management’s own assumptions about the 
assumptions a market participant would use in pricing the asset or liability (examples 
include private equity investments, certain commercial mortgage whole loans, and long-
dated or complex derivatives including certain foreign exchange options and long-dated 
options on gas and power).

Liabilities utilizing Level 3 inputs include liabilities for contingent purchase consideration.

Valuation Techniques

Equity Securities and Mutual Funds - Level 1

Investments for which market quotations are readily available are valued at the sale price on their 
principal exchange, or official closing bid price for certain markets.

Contingent Purchase Consideration Liability - Level 3

Purchase consideration for some acquisitions made by the Company includes contingent consideration 
arrangements. Contingent consideration arrangements are primarily based on meeting EBITDA and 
revenue targets over periods from two to four years. The fair value of contingent consideration is 
estimated as the present value of future cash flows resulting from the projected revenue and earnings of 
the acquired entities.

The following fair value hierarchy table presents information about the Company’s assets and liabilities 
measured at fair value on a recurring basis as of December 31, 2015 and 2014:

The table below sets forth a summary of the changes in fair value of the Company’s Level 3 liabilities for

The fair value of the contingent purchase consideration liability is based on projections of revenue and 
earnings for the acquired entities that are reassessed on a quarterly basis. As set forth in the table above, 
based on the Company's ongoing assessment of the fair value of contingent consideration, the Company 
recorded a net increase in the estimated fair value of such liabilities for prior period acquisitions of $45 
million for the year ended December 31, 2015. A 5% increase in the above mentioned projections would 
increase the liability by approximately $24 million. A 5% decrease in the above mentioned projections 
would decrease the liability by approximately $37 million.

Long-Term Investments

The Company holds investments in certain private companies, public companies and certain private 
equity investments that are accounted for using the equity method of accounting. The carrying value of 
these investments amounted to $347 million and $388 million at December 31, 2015 and 2014, 
respectively.  

The Company's investments in private equity funds were $76 million and $61 million at December 31, 
2015 and December 31, 2014, respectively. The carrying values of these private equity investments 
approximates fair value. The underlying private equity funds follow investment company accounting, 
where investments within the fund are carried at fair value. The Company records in earnings, investment 
gains/losses for its proportionate share of the change in fair value of the funds. These investments would 
be classified as Level 3 in the fair value hierarchy and are included in other assets in the consolidated 
balance sheets.

Alexander Forbes: During 2014, the Company acquired a 34% interest in South Africa-based Alexander 
Forbes Group Holding Limited ("Alexander Forbes") becoming a strategic shareholder after Alexander 
Forbes successfully launched an initial public offering. Mercer purchased its stake in Alexander Forbes in 
two tranches at 7.50 South African Rand per share for aggregate purchase consideration of 
approximately $300 million. 

Upon completion of the acquisition, the purchase price of the Alexander Forbes shares exceeded the 
Company's share of the equity in net assets by approximately $146 million. The majority of this basis 
difference resulted from the excess of the Company’s purchase price for the Alexander Forbes common 
stock acquired over the book value of Alexander Forbes’ net assets. Substantially all of this basis 
difference was allocated, based on the fair values of Alexander Forbes’ assets and liabilities, to the value 
of investment contracts, customer contracts and relationships acquired and technology related intangible 
assets, related deferred tax liability and goodwill. The basis difference related to these intangible assets 
(excluding goodwill) is recorded as additional amortization expense over their estimated lives. The basis 
difference related to the goodwill will be recognized upon disposition of our investment.

Alexander Forbes principally focuses on employee benefits and investment solutions for institutional 
clients, and financial wellbeing and retail financial solutions for individual clients. Services include 
retirement funds and investment consulting, actuarial and administration services, employee risk benefits 
and health-care consulting, multi-manager investments solutions, and personal lines and business 
insurance.

As of December 31, 2015, the carrying value of the Company’s investment in Alexander Forbes was 
approximately $230 million. As of December 31, 2015, the market value of the approximately 443 million 
shares owned by the Company, based on the December 31, 2015 closing share price of 5.78 South 

90

African Rand per share, was approximately $166 million. During 2015, the share price of Alexander 
Forbes ranged from 5.32 Rand to 10.38 Rand. The trading price first dropped below MMC's purchase 
price in November 2015. The Company considered several factors related to its investment in Alexander 
Forbes, including its financial position, the near- and long-term prospects of Alexander Forbes and the 
broader South African economy and capital markets, the length of time and extent to which the market 
value was below cost, and the Company’s intent and ability to retain the investment for a sufficient period 
of time to allow for anticipated recovery in market value. As a result, the Company determined the 
investment was not impaired.

The carrying value of the Company’s investment in Alexander Forbes and its other investments in private 
companies that are accounted for using the equity method of accounting is included in other assets in the 
consolidated balance sheets and the related results are included in revenue in the consolidated income 
statements. The Company records its share of income or loss on its equity method investments on a one 
quarter lag basis.

On February 24, 2015, Mercer purchased shares of common stock of Benefitfocus (NASDAQ:BNFT) 
constituting approximately 9.9% of BNFT's outstanding capital stock as of the acquisition date. The 
purchase price for the BNFT shares and certain other rights and other consideration was approximately 
$75 million. The Company has elected to account for this investment under the cost method of accounting 
as the shares purchased are categorized as restricted and cannot be sold for more than one year. 
Effective January 1, 2017, these shares will be be accounted for as available for sale securities and 
classified as Level 2 in the fair value hierarchy and included in other assets in the consolidated balance 
sheets. The value of the BNFT shares based on the closing price on the NASDAQ at December 31, 2015 
and without regard to the restrictions on sale was approximately $102 million.

The summarized financial information presented below reflects the aggregated financial information of all 
significant equity method investees as of and for the twelve months ended September 30 of each year (or 
portion of those twelve months the Company owned its investment), consistent with the Company’s 
recognition of the results of its equity method investments on a one quarter lag. The investment income 
information presented below reflects the net realized and unrealized gains/losses, net of expenses, 
related to the Company's investments in several private equity funds. Certain of the Company’s equity 
method investments, including Alexander Forbes, have unclassified balance sheets. Therefore, the asset

11.    Long-term Commitments

The Company leases office facilities, equipment and automobiles under non-cancelable operating leases. 
These leases expire on varying dates, in some instances contain renewal and expansion options, do not 
restrict the payment of dividends or the incurrence of debt or additional lease obligations, and contain no 
significant purchase options. In addition to the base rental costs, occupancy lease agreements generally 
provide for rent escalations resulting from increased assessments for real estate taxes and other charges. 
Approximately 98% of the Company’s lease obligations are for the use of office space.

The consolidated statements of income include net rental costs of $381 million, $393 million and $403 
million for 2015, 2014 and 2013, respectively, after deducting rentals from subleases ($14 million in 2015,

The senior notes in the table above are publically registered by the Company with no guarantees 
attached.

In September 2015, the Company issued $600 million of 3.75% 10.5-year senior notes. The Company 
used the net proceeds for general corporate purposes.

In March 2015, the Company issued $500 million of 2.35% five-year senior notes. The Company used the 
net proceeds for general corporate purposes.

In September 2014, the Company issued $300 million of 2.35% five-year senior notes and $500 million of 
3.50% 10.5-year senior notes. In October 2014, a significant portion of the net proceeds of this offering 
were used to redeem $630 million of debt, including $230 million of 5.75% senior notes due in September 
2015 and $400 million of 9.25% senior notes due in 2019. Total cash outflow related to this transaction 
was approximately $765 million, including a $137 million cost for early redemption, which was reflected as 
a charge in the consolidated statements of income in the fourth quarter of 2014.

In May 2014, the Company issued $600 million of 3.50% ten-year senior notes. The net proceeds of this 
offering were used for general corporate purposes, which included the repayment of $320 million of the 
existing 5.375% senior notes, which matured on July 15, 2014.

On November 24, 2015, the Company and certain of its foreign subsidiaries amended a $1.2 billion multi-
currency five-year revolving credit facility, that was due to expire in March 2019, into a new $1.5 billion 
multi-currency five-year unsecured revolving credit facility. The interest rate on this facility is based on 
LIBOR plus a fixed margin which varies with the Company's credit ratings. This facility expires in 
November 2020 and requires the Company to maintain certain coverage and leverage ratios which are 
tested quarterly. There were no borrowings outstanding under this facility at December 31, 2015.

The Company and certain of its foreign subsidiaries previously maintained a $1.2 billion multi-currency 
five-year revolving credit facility. The facility was previously due to expire in March 2019 and was in effect 

93

 
until November 2015. There were no borrowings outstanding under this facility at the time it was 
amended.

The Company has a $150 million uncommitted bank credit line. There were no borrowings under this 
facility at December 31, 2015.

In December 2012, the Company closed on a $50 million, three-year term loan facility, which was 
terminated on October 30, 2015.

Additional credit facilities, guarantees and letters of credit are maintained with various banks, primarily 
related to operations located outside the United States, aggregating $229 million at December 31, 2015 
and $260 million at December 31, 2014. There was $0.4 million outstanding borrowings under these 
facilities at December 31, 2015 and $0.6 million outstanding borrowings under these facilities at 
December 31, 2014.

Scheduled repayments of long-term debt in 2016 and in the four succeeding years are $12 million, $263 
million, $262 million, $313 million and $514 million, respectively.

Fair value of Short-term and Long-term Debt

The estimated fair value of the Company’s short-term and long-term debt is provided below. Certain 
estimates and judgments were required to develop the fair value amounts. The fair value amounts shown 
below are not necessarily indicative of the amounts that the Company would realize upon disposition, nor 
do they indicate the Company’s intent or need to dispose of the financial instrument.

The fair value of the Company’s short-term debt consists primarily of term debt maturing within the next 
year and its fair value approximates its carrying value. The estimated fair value of a primary portion of the 
Company's long-term debt is based on discounted future cash flows using current interest rates available 
for debt with similar terms and remaining maturities. Short- and long-term debt would be classified as 
Level 2 in the fair value hierarchy.

13.    Integration and Restructuring Costs

In 2015, the Company implemented restructuring actions which resulted in costs totaling $28 million.   
Restructuring costs consist primarily of severance and benefits, costs for future rent and other real estate 
costs. These costs were incurred as follows: Risk and Insurance Services—$8 million; Consulting—$8 
million; and Corporate—$12 million.

Details of the restructuring liability activity from January 1, 2014 through December 31, 2015, including 
actions taken prior to 2015, are as follows:

As of January 1, 2013, the liability balance related to restructuring activity was $170 million. In 2013, the 
Company accrued $22 million and had cash payments and other adjustments of $68 million related to 
restructuring activities that resulted in the liability balance at January 1, 2014 reported above.

The expenses associated with the above initiatives are included in compensation and benefits and other 
operating expenses in the consolidated statements of income. The liabilities associated with these 
initiatives are classified on the consolidated balance sheets as accounts payable and accrued liabilities, 
other liabilities, or accrued compensation and employee benefits, depending on the nature of the items.

14.    Common Stock

During 2015, the Company repurchased 24.8 million shares of its common stock for total consideration of 
$1.4 billion. In May 2015, the Board of Directors renewed the Company's share repurchase program, 
allowing management to buy back up to $2 billion of the Company's common stock. The Company 
remains authorized to purchase additional shares of its common stock up to a value of approximately 
$1.2 billion. There is no time limit on the authorization. During 2014, the Company purchased 15.5 million 
shares of its common stock for total consideration of $800 million.

15.    Claims, Lawsuits and Other Contingencies 

Litigation Matters

The Company and its subsidiaries are subject to a significant number of claims, lawsuits and proceedings 
in the ordinary course of business. Such claims and lawsuits consist principally of alleged errors and 
omissions in connection with the performance of professional services, including the placement of 
insurance, the provision of actuarial services for corporate and public sector clients, the provision of 
investment advice and investment management services to pension plans, the provision of advice relating 
to pension buy-out transactions and the provision of consulting services relating to the drafting and 
interpretation of trust deeds and other documentation governing pension plans. These claims may seek 
damages, including punitive and treble damages, in amounts that could, if awarded, be significant. In 
establishing liabilities for errors and omissions claims in accordance with FASB ASC Subtopic No. 450-20 
(Contingencies-Loss Contingencies), the Company uses case level reviews by inside and outside 
counsel, an internal actuarial analysis and other analysis to estimate potential losses. A liability is 
established when a loss is both probable and reasonably estimable. The liability is reviewed quarterly and 
adjusted as developments warrant. In many cases, the Company has not recorded a liability, other than 
for legal fees to defend the claim, because we are unable, at the present time, to make a determination 
that a loss is both probable and reasonably estimable.

To the extent that expected losses exceed our deductible in any policy year, the Company also records an 
asset for the amount that we expect to recover under any available third-party insurance programs. The 
Company has varying levels of third-party insurance coverage, with policy limits and coverage terms 
varying significantly by policy year.

Governmental Inquiries and Enforcement Matters

Our activities are regulated under the laws of the United States and its various states, the European 
Union and its member states, and the other jurisdictions in which the Company operates. In the ordinary 
course of business, the Company is also subject to subpoenas, investigations, lawsuits and other 
regulatory actions undertaken by governmental authorities.

Other Contingencies-Guarantees

In connection with its acquisition of U.K.-based Sedgwick Group in 1998, the Company acquired several 
insurance underwriting businesses that were already in run-off, including River Thames Insurance 
Company Limited ("River Thames"), which the Company sold in 2001. Sedgwick guaranteed payment of 
claims on certain policies underwritten through the Institute of London Underwriters (the "ILU") by River 
Thames. The policies covered by this guarantee were reinsured up to £40 million by a related party of 
River Thames. Payment of claims under the reinsurance agreement is collateralized by segregated 
assets held in a trust. As of December 31, 2015, the reinsurance coverage exceeded the best estimate of 
the projected liability of the policies covered by the guarantee. To the extent River Thames or the 

95

reinsurer is unable to meet its obligations under those policies, a claimant may seek to recover from the 
Company under the guarantee.

From 1980 to 1983, the Company owned indirectly the English & American Insurance Company (“E&A”), 
which was a member of the ILU. The ILU required the Company to guarantee a portion of E&A's 
obligations. After E&A became insolvent in 1993, the ILU agreed to discharge the guarantee in exchange 
for the Company's agreement to post an evergreen letter of credit that is available to pay claims by 
policyholders on certain E&A policies issued through the ILU and incepting between July 3, 1980 and 
October 6, 1983. Certain claims have been paid under the letter of credit and the Company anticipates 
that additional claimants may seek to recover against the letter of credit.

Kroll-related Matters

Under the terms of a stock purchase agreement with Altegrity, Inc. ("Altegrity") related to Altegrity's 
purchase of Kroll from the Company in August 2010, a copy of which is attached as an exhibit to the 
Company's Quarterly Report on Form 10-Q for the period ended June 30, 2010, the Company agreed to 
provide a limited indemnity to Altegrity with respect to certain Kroll-related litigation and regulatory 
matters.

*  *  *  *

The pending proceedings and other matters described in this Note 15 on Claims, Lawsuits and Other 
Contingencies may expose the Company or its subsidiaries to liability for significant monetary damages 
and other forms of relief. Where a loss is both probable and reasonably estimable, the Company 
establishes liabilities in accordance with FASB ASC Subtopic No. 450-20 (Contingencies-Loss 
Contingencies). Except as described above, the Company is not able at this time to provide a reasonable 
estimate of the range of possible loss attributable to these matters or the impact they may have on the 
Company's consolidated results of operations, financial position or cash flows. This is primarily because 
these matters are still developing and involve complex issues subject to inherent uncertainty. Adverse 
determinations in one or more of these matters could have a material impact on the Company's 
consolidated results of operations, financial condition or cash flows in a future period.

16.    Segment Information

The Company is organized based on the types of services provided. Under this organizational structure, 
the Company’s segments are:

Risk and Insurance Services, comprising insurance services (Marsh) and reinsurance services 
(Guy Carpenter); and

Consulting, comprising Mercer and Oliver Wyman Group

The accounting policies of the segments are the same as those used for the consolidated financial 
statements described in Note 1. Segment performance is evaluated based on segment operating income, 
which includes directly related expenses, and charges or credits related to integration and restructuring 
but not the Company’s corporate-level expenses. Revenues are attributed to geographic areas on the 
basis of where the services are performed.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Marsh & McLennan Companies, Inc. 
New York, New York

We have audited the accompanying consolidated balance sheets of Marsh & McLennan Companies, Inc. 
and subsidiaries (the "Company") as of December 31, 2015 and 2014, and the related consolidated 
statements of income, comprehensive income, cash flows and equity for each of the three years in the 
period ended December 31, 2015.  These financial statements are the responsibility of the Company’s 
management.  Our responsibility is to express an opinion on these financial statements based on our 
audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight 
Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of material misstatement.  An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.  
An audit also includes assessing the accounting principles used and significant estimates made by 
management, as well as evaluating the overall financial statement presentation.  We believe that our 
audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial 
position of Marsh & McLennan Companies, Inc. and subsidiaries as of December 31, 2015 and 2014, and 
the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2015, in conformity with accounting principles generally accepted in the United States of 
America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight 
Board (United States), the Company’s internal control over financial reporting as of December 31, 2015, 
based on the criteria established in Internal Control-Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 24, 
2016 expressed an unqualified opinion on the Company’s internal control over financial reporting.

Internal Control over Financial Reporting.

(a)  Management’s Annual Report on Internal Control Over Financial Reporting

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Marsh & McLennan Companies, Inc. is responsible for establishing and maintaining 
adequate internal control over financial reporting for the Company. The Company’s internal control over 
financial reporting is designed to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation of financial statements for external purposes in accordance with generally 
accepted accounting principles.

The Company’s internal control over financial reporting includes those policies and procedures relating to 
the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the Company; the recording of all necessary transactions to permit the 
preparation of the Company’s consolidated financial statements in accordance with generally accepted 
accounting principles; the proper authorization of receipts and expenditures in accordance with 
authorizations of the Company’s management and directors; and the prevention or timely detection of the 
unauthorized acquisition, use or disposition of assets that could have a material effect on the Company’s 
consolidated financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk 
that controls may become inadequate because of changes in conditions, or that the degree of compliance 
with the policies or procedures may deteriorate.

Management evaluated the effectiveness of the Company’s internal control over financial reporting as of 
December 31, 2015 under the supervision and with the participation of the Company’s principal executive 
and principal financial officers. In making this evaluation, management used the criteria set forth by the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—
Integrated Framework issued in 2013. Based on its evaluation, management determined that the 
Company maintained effective internal control over financial reporting as of December 31, 2015.

Deloitte & Touche LLP, the Independent Registered Public Accounting Firm that audited and reported on 
the Company’s consolidated financial statements included in this annual report on Form 10-K, also issued 
an audit report on the effectiveness of the Company’s internal control over financial reporting as of 
December 31, 2015.

(b)  Audit Report of the Registered Public Accounting Firm.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Marsh & McLennan Companies, Inc. 
New York, New York

We have audited the internal control over financial reporting of Marsh & McLennan Companies, Inc. and 
subsidiaries (the "Company") as of December 31, 2015, based on criteria established in Internal Control - 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission.  The Company’s management is responsible for maintaining effective internal control over 
financial reporting and for its assessment of the effectiveness of internal control over financial reporting, 
included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting.  
Our responsibility is to express an opinion on the Company’s internal control over financial reporting 
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight 
Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable 
assurance about whether effective internal control over financial reporting was maintained in all material 
respects.  Our audit included obtaining an understanding of internal control over financial reporting, 
assessing the risk that a material weakness exists, testing and evaluating the design and operating 
effectiveness of internal control based on the assessed risk, and performing such other procedures as we 
considered necessary in the circumstances.  We believe that our audit provides a reasonable basis for 
our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, 
the company's principal executive and principal financial officers, or persons performing similar functions, 
and effected by the company's board of directors, management, and other personnel to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements for external purposes in accordance with generally accepted accounting principles.  A 
company’s internal control over financial reporting includes those policies and procedures that (1) pertain 
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally 
accepted accounting principles, and that receipts and expenditures of the company are being made only 
in accordance with authorizations of management and directors of the company; and (3) provide 
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of 
collusion or improper management override of controls, material misstatements due to error or fraud may 
not be prevented or detected on a timely basis.  Also, projections of any evaluation of the effectiveness of 
the internal control over financial reporting to future periods are subject to the risk that the controls may 
become inadequate because of changes in conditions, or that the degree of compliance with the policies 
or procedures may deteriorate. 

In our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2015, based on the criteria established in Internal Control - Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight 
Board (United States), the consolidated financial statements as of and for the year ended December 31, 
2015 of the Company and our report dated February 24, 2016 expressed an unqualified opinion on those 
financial statements.

(c)  Changes in Internal Control Over Financial Reporting

There were no changes in the Company’s internal control over financial reporting identified in connection 
with the evaluation required by Rules 13a-15(d) or 15d-15(d) under the Securities Exchange Act of 1934 
that occurred during the quarter ended December 31, 2015 that have materially affected, or are 
reasonably likely to materially affect, the Company’s internal control over financial reporting.

Item 9B.      Other Information.

In light of the impact of foreign exchange globally, the Compensation Committee (the "Committee") of the 
Board of Directors of the Company granted performance stock unit awards on February 22, 2016 with a 
three-year adjusted earnings per share ("EPS") growth performance measure that excludes the impact of 
currency exchange rate fluctuations.

With respect to the performance stock unit awards granted in 2015 ("2015 PSUs"), the three-year 
adjusted EPS growth performance measure selected by the Committee did not expressly reference the 
impact of currency exchange rate fluctuations. On February 22, 2016, the Committee amended the 
adjusted EPS performance measure for the outstanding 2015 PSUs, including awards held by the 
Company’s executive officers, to exclude the impact of currency exchange rate fluctuations.  

Accordingly, the relevant definition for "adjusted EPS growth" for outstanding performance stock unit 
awards granted in 2016 and 2015 is: earnings per share from continuing operations calculated in 
accordance with accounting principles generally accepted in the U.S. ("GAAP"), adjusted for the impact of 
"noteworthy items" (adjusted diluted EPS), and adjusted further to exclude the impact of currency 
exchange rate fluctuations, for the variation between actual and budgeted results for Marsh & McLennan 
Risk Capital Holdings, Ltd. (MMRCH), the legal entity through which the Company owns interests in 
private equity funds and other investments, and for the costs related to the early extinguishment of debt.

Also on February 22, 2016, the Committee increased the annual long-term incentive award target grant 
date fair value for the Company's CEO, Dan Glaser, from $8,000,000 to $9,500,000.
